I have a few more items that I have found recently:

1000 ml amber wide mouth HDPE Nalgene bottles - brand new - These sell elsewhere for $10 apiece but I have 2 packages of 6 that I will sell for $2 per bottle or $10 per package of 6 (plus postage). See below

http://www.shopping.com/nalgene-nalgene-amber-bottle-wide-mo... or
http://www.amazon.com/dp/B003OBYV70/ref=biss_dp_t_asn

I also have some white plastic containers with black phenolic screw tops, they are also HDPE, about 40 oz, diameter is 80 mm, height is 130 mm. I would sell these for $2 each. I believe that they were intended to be secondary containment for shipping small chemical bottles. But they are great for solids, powders, holding septa or other small parts, nails, screws, etc. They should be OK for liquids, but they are not ideal for them. I have a few dozen of these.

shipping is $198? from Mars?

Dr.Bob - 27-11-2012 at 17:42

I am now out of most 24/40 single joint rbfs, still have a few evaporating flasks and a few 3 necks in 24/40. I have one or two coil condensers left in 24/40, for $25, which I recently found, some addition funnels, and lots of odd adapters, but running out of much in 24/40.

I do still have a number of 14/20 flasks and pieces, which I just updated the inventory of, so if you are interested in 14/20, this is the time to act, as I am just starting to run out of those in a few larger sizes. But I am out of most of the adapters and condensers needed for a complete kit. I do still have some adapters and more esoteric pieces. If people want to buy multiples of one flask or a mix of many flasks, I am very willing to make deals.

I am also running out of crystallizing dishes and beakers, but still have lots of filter flasks, smaller erlenmeyers, and much more. Please see the attached file for the most current list.

Here are most of the rings I have left, from about 2" to 7". They are $5 each.

thelonious - 27-12-2012 at 20:35

My feedback on Dr.Bob: I've made several purchases with him, and I've got to say, I'm impressed. Not only did he put extra stuff in every shipment, but he replaced several items for free when they arrived broken! I'm definitely buying from him again in the future.

7-7-7 - 1-1-2013 at 13:08

Hey Doc are those Nalgene Bottles autoclavable?

I too am very happy with previous order from Dr. Bob

Dr.Bob - 2-1-2013 at 08:21

I am not sure if the Nalgene bottles are autoclavable. I have a few varieties, most of these are made of polypropylene, PP. If the Nalgene site says that there standard Boston round PP bottles are autoclavable, then I would expect all of these to be as well. If you know that some types are autoclavable, I can try to find those types in my collection or find a comparable one. But I Googled a couple types of bottles I have had and the specs say that they can be autoclaved, with the lid loose (so it does not stick shut, I believe).

Dr.Bob please explain how the transaction is made (i.e how am i supposed to send you money and how are you supposed to send me the equipments)..

Hexavalent - 2-1-2013 at 13:47

AFAIK, you send him the money online via PayPal, and he, upon receiving your payment, dispatches the items in the mail.

sinlyn - 3-1-2013 at 00:04

I might be interested in some of the ground glass labware.

K12Chemistry - 6-1-2013 at 11:34

I would love it if I could get anything!

Cloner - 8-1-2013 at 01:22

I have a number of used bunsen burners and bunsen burner tripods as well as mercury thermometers to get rid of. PM me if you are interested.

I am considering to throw away the tripods because they are rusty, the other items can certainly be useful to someone.

Darkblade48 - 8-1-2013 at 20:54

I am curious as to shipping to Canada. What options are available?

Dr.Bob - 10-1-2013 at 11:51

I have shipped a number of items to Canada. For packages less than 4 pounds, it is pretty easy, simple customs with no issues so far, and costs about $16-20 for 4 pounds. For packages over that, it gets more expensive per pound until it is over about 10 or 12 pounds, plus there is more paperwork and customs possible issues, although most people have not reported any serious delays (usually under a month).

My main issue is that they are rough on packages during this handling, so that adds to the problem, and there is no practical insurance for international mail, so either I have to charge a little extra for that risk and replace what breaks for free (self insured), which I have done, or you have to accept that some items may break, which I try to avoid.

For example, I had one person who wanted a large order of large fragile items, but wanted to keep the shipping very low, so I tried to pack things in as few boxes as possible to keep the overall costs down, and several items of a large order were broken, due to visibly rough handling (dents in boxes). So I replaced about half of the broken glass for free, but that is not a good option for anyone. So the best solution is to mostly buy smaller things or less fragile stuff, as they are easy to ship internationally, or be willing to pay to cost for well padded and packed items.

I need to update the list and report, I'll do that this weekend if I can. I have sold a lot of stuff in the lat month, so a few more items are running out.

[Edited on 11-1-2013 by Dr.Bob]

Darkblade48 - 10-1-2013 at 21:16

Hmm, I'll take a look through the list again; there were definitely some items that I was interested in.

I take the previous spreadsheet was the latest up to date stock you still have?

Dr.Bob - 20-1-2013 at 20:06

Here is a more recent list. I have run out of a few more items, such as 500 ml grad cyl, 1000 ml 3 necks flasks, and a few crystallizing dishes. But there is still a lot left. Here is the latest list. I also have a couple of Corning PC-320 stirring hotplates I just found that work OK, but are a bit dirty. I am asking $90 for each.

Just found 2 more 2L sep funnels with Teflon stopcocks BUT the drip tips are broken off most or all of the way. They would be $40, due to the damage. Otherwise they are good condition, with stopper and stopcock.

Also just found more new 4 and 8 ml vials in packages of 144, with black phenolic caps with rubber liners.

I also keep finding more small volumetric flasks, I have lots from 2 to 25 ml, and a few larger ones left as well.

Thanks to everyone for their help finding this glassware a home.

D-glucose - 24-1-2013 at 20:36

do you have any scintillation vials?

Dr.Bob - 24-1-2013 at 20:48

I have a bag full of plastic scint vials (maybe about 100), Anyone, make me an offer. I have a few loose glass ones, but I don't think I have any boxes of 100 left, although I am not sure. I do have some other 4 and 6 dram glass vials (16 and 24 ml) left with black phenolic caps, I need to create pricing for them, I just found more, and haven't priced them yet.

D-glucose - 24-1-2013 at 20:53

ok, thank you.

smaerd - 26-1-2013 at 07:32

Thanks again Dr. Bob! Had another order, probably my 6th, and all I have to say is now is as good of a time to be buying from the guy as ever. Edit - my home lab wouldn't be nearly what it is today without him. Don't be afraid to ask him things that aren't on the list!

[Edited on 26-1-2013 by smaerd]

Dr.Bob - 26-1-2013 at 18:52

Here are some of the fritted funnels I have left. The sizes range from 15 ml to 350 ml (volume of the top part). I have simple funnels, as well as 14/20 and 24/40 jointed ones. The frits are F, M and C. I have most frit porosity types in most sizes and styles, but not all. These photos DO NOT include the larger or longer ones, including the ones meant for chromatography, which I am still trying to organize. I have several more boxes of these available, some of those are dirtier or larger. I also have some smaller buchners, glass frits and other odd pieces, most are listed in the spreadsheet.

Many of these are Chemglass, some are Pyrex, Ace or other US brands. But most are the same dimensions as shown in the Chemglass specs (see below for links). No crappy imported ones. Pricing is in the inventory list spreadsheet.

If you want an assortment of sizes or types, I am willing to give a discount on the prices listed in the spreadsheet based on the number wanted. I even have a couple larger ones still new in the box (for more, of course). If you want better photos, please send me a u2u with an email address that I can send photos to, or email me at craigslistinnc at gmail.com and I will reply with my real email (get too much spam there).

PS, One note, if you have sent me a note, u2u or request, and I have not gotten back, please remind me. The u2u system is hard to find old messages in, and I have dozens of conversations going on, so sometimes I am slow to respond, as well as I have lost some messages sometimes.

Here are some 14/20 items left still. First is a small kit of remaining 14/20 dist adapters, accessories, and flasks. Then I have some still heads, simple medium length condenser head and other bits, a vacuum jacketed dist. head, a smaller head, and a distillation fraction collector (bull type) for 4 flasks. I can add items to the 14/20 kits if someone is interested but I am running out of many items like simple 14/20 condensers. Pricing is thus: kit of 14/20 flasks and adapters - $80 including a short path. The 14/20 still heads are $40 and $50 for the 100 or 250 ml size. The simple medium path is $30, the fritted 14/20 column is $15, the vac jacket dist head is $100, the medium sized head (4th photo) is $60, and the bull type fraction collector is $40 (w/o flasks, or $50 with 4 rb flasks).

That fourth picture!
I was thinking how nice it would be to have one of those... but I already have a standard Liebig, so I'll let someone else have it.

Dr.Bob - 9-2-2013 at 20:24

Here are some odd flasks that I have left for sale.

a) 2 1000 ml 3 necks with center 34/45 joints and side 24/40 joints. Both are worn a bit, the right one has a chip on the center joint. Right one is $20 left one is $15.

b) 1000 ml rbf w/ 3 29/42 joints - the center joint comes with bonus free 14/20 adapter stuck in it. This would be $10, you might be able to get the joint out, stopper it, or just use it as is.

c & d) 1000 ml FLAT bottom flask with all 24/40 joints. $20 NOT for vacuum use, but might be OK for gentle heating. Not sure what this is ideal for, but nearly new condition. Ace Glass brand. c) shows it sitting on its own d) shows bottom view.

e) 1000 ml 3 neck with all 24/40 joints, vertical joints. In good shape, last 1L 3 neck with all 2/40 joints. Ace glass $20

Here are the 2 and 3 L flasks

a & b) 2000 ml 1 neck 29/42 - Chemglass brand, VERY thick glass, NOT suitable for heating with a flame, only a heating mantle or oil bath. - $12

c) 2000 ml 3 neck with center 34/45 joint, side 29/42 joints Repaired by Chemglass, a star crack was fixed. $25

d) 2000 ml 3 neck with center 34/45 joint, side 29/42 joints. $25

e) 3000 ml 1 neck with 29/42 joint. One is Chemglass, other looks like Ace or similar brand. Both are VERY thick glass, NOT suitable for heating with a flame, only a heating mantle or oil bath. $18 each.

Note: I am currently out of 24/40 to 29/42 adapters, trying to find any left, but I won't likely find any more.

Dr.Bob - 9-2-2013 at 20:46

And lastly, here are a few odd things I found while looking for other things.

a) a few more flat bottomed flasks. One 500 ml (6$), 3 250 ml (5$) and one 125 ml (4$)

b) A 3000 ml beaker, with 2 very small chips on the lip (right rear). Otherwise great condition. I think they could both be fixed either with some extra fine sand paper (the black SiC stuff) or a very minor flame polishing. $10

c) Two enormously long west condensers. One is 600 mm ($35) the shorter is only 500 mm ($30). These were mixed in with columns that I was sorting through recently. They will not be trivial to ship, so please realize that the shipping may cost extra due to the length of these.

If you are interested in any of the items listed, I can provide more information, just send an email or u2u to me. If you want to know shipping costs, please let me know what state or country you are in. Thanks for looking.

Dr.Bob - 13-2-2013 at 05:13

Just to update people, I have sold the 2 PC-320 stirring hotplates now, and have quite a few offers on the recently posted glassware, which I am answering as fast as I can, trying to sell things in the order that offers to buy came in, so if I am slow to respond, it is because I am trying to answer the requests in order that they were made. That seems the most fair way to do it. Once I get caught up with this batch I will try to post a new list as quite a bit has sold lately, and I have a number of pending inquiries, so the list keeps changing.

Thanks again to everyone who has bought stuff as well as many people for their patience with me, when I am slow to respond.

Here is a photo of a bunch of bottles that I have available. I would sell the smaller ones for $1 each, the larger ones for $2 each (500 ml and up). If you want more than 10, I can do even better. I have lids for the 1L ones, just couldn't find them right now. Use the URL to see a better photo. I'm still trying to figure out why the photo won;t display from the url...

Here is the latest list of glassware. I have recently found a few more smaller 24/40 flasks (50, 100, 250 ml), as well as a few 250 ml erlenmeyers, 500 ml grad cyl. and a few other things I thought I was out of.

I also found another box of 24/40 2 & 3 L flasks, which I will post photos of soon.

What's the cost of shipping the UK for say 10/20KG weight?

Dr.Bob - 14-3-2013 at 13:11

A 4 lb box to the UK is about $35-36 US. Up to 4 pounds is easy. Over 4 pounds, there are customs forms and the rate is about $8/ pound, but it does go down a bit over 10 pounds. So the short answer is more than most items are worth. But smaller items are much easier to afford, like 14/20 glassware, stir bars, smaller flasks and filters, etc.

carbonated - 14-3-2013 at 18:46

Just placed an order on a heating mantle + a few assorted items with the Doc. Looking forward to receiving all of it!

MyNameIsUnnecessarilyLong - 16-3-2013 at 21:59

Bob, do you have any class 1/E2 calibration weights for analytical scales?

looking for a couple 100g or a single 200g weights...

Dr.Bob - 18-3-2013 at 05:52

I think I have seen some weights like that somewhere in a box, but have absolutely no idea exactly where now, or what wight they were. But I will keep an eye out for them and let you know if I find any.

BTW, I just got about 60 boxes of books in to sort through recently, so I have been backed up a bit on the science supplies, so I have been a bit slow to answer messages. I am trying to get to them as fast as I can, so my apologies if I am slow.

I do have some old chemistry books among them, once I get caught up a bit, I may try to post a list or maybe even scan in a few that might be of interest. Many are too old or too specific to be of general interest, but I think some might be useful. And the bigger ones just take too long to scan in and general massive files. One day I need to learn how to use the software to edit/compress .pdf files.

MyNameIsUnnecessarilyLong - 19-3-2013 at 15:56

Do you have any stereo microscopes for sale?

Dr.Bob - 20-3-2013 at 05:01

Not currently. I need to try to finish up cleaning my garage and basement so as to find any remaining boxes. I shoved them everywhere I could when I got this glassware, as I could not fit them all in, so I tended to just stick them in every nook and cranny of my basement, garage, etc. I keep finding boxes under other stuff and behind things.

CaptainOfSmug - 20-3-2013 at 18:47

Do you have a dessicator by anychance?

Fantasma4500 - 26-3-2013 at 07:51

i think you should write shortly what you have left, beakers of size to size.. but you are shipping from usa, right? if so it might be hard economically for us in europe to buy some as they charge a tonne of money for importing :/

Hockeydemon - 27-3-2013 at 01:40

I would also appreciate a quick recap of what you have available still. The large lot of glassware I ordered from Ebay never came and I had to have Ebay insurance give me my money back

. So I now have a lot of glassware I need to acquire still..

Specifically I need a separatory funnel, but I'd be fine with an addition funnel.
A 24/40 round boiling flask
glass tubing & various rubber stoppers
chemical vials/storage containers
A male-male 24/40 adapter
500mL Buchner flask & funnel
A Burrette
A graduated cylinder (mines only 25mL)
A volumetric flask

I also have this stupid Liebig condenser that is useless until I figure out what to stick in the non-ground glass joint top.

I don't expect you to have most of those, but it's what I need off the top of my head..

[Edited on 27-3-2013 by Hockeydemon]

Dr.Bob - 27-3-2013 at 05:43

To answer a few questions.

I don't have any desiccators left now, sorry. I only had a few.

The list posted on 3-13 (see above) is still mostly correct, almost entirely out of beakers, except for a few small ones, and the shipping to Europe makes them very expensive. What I have lots of still is erlenmeyer flasks, volumetrics, filter flasks, funnels and frits, stirbars, and much more. I am running out of much, but not all 24/40 glassware and beakers.

I have separatory funnels up to 1L and smaller size addition funnels (plus a 2 L one).
24/40 round boiling flasks (50, 100, a few 250 ml)
glass tubing & various rubber stoppers (have a few stoppers left)
chemical vials/storage containers - lots, see list and photos above for some of them.
A male-male 24/40 adapter - yep, have a few types
500mL Buchner flask & funnel - scads of them
A Burrette - might have just found one more, have to make sure the stopcock works.
A graduated cylinder (mines only 25mL) - have all sizes
A volumetric flask - have all sizes

Just send me a u2u with more size desires in the categories, and I can get back with more info, if you have an email address, that works much better, as I can't attach photos or files in u2u's. If people can't open the excel list, I can post a txt file or other format.

Also, since people ask a lot, I normally use Paypal (the Ebay payment system) for purchases, but can arrange to sell via Ebay, Amazon (in some cases), money order, cash, Western Union, gold, etc. I have a few of these items already listed there, but since they charge high fees, the prices are mostly higher then posted here.

[Edited on 27-3-2013 by Dr.Bob]

Hockeydemon - 3-4-2013 at 01:08

I sent you a U2U last week with my email & list of items I'd like to buy. Just want to confirm you got it because I haven't heard back. Also I need a stir plate if you happen to have one, I know you're already out of hot plates. I just found out I have 20 days of vacation time saved up for work that I have to cash in by the end of the month so whenever that check comes I'll be able to afford more than $150 worth of stuff

mayko - 3-4-2013 at 14:36

I discovered that I am not that far from Dr. Bob, and had the good fortune of meeting him! I feel like I got a really good deal, and am excited about finally having some serious chemical infrastructure. He also gave me a handbook of practical organic chemistry, something I had been lacking in hardcopy.

Thanks again!

Vogel's Textbook of Practical Organic Chemistry??? I really want that book! I just can't justify paying $225 for a used copy when I have the ebook - even if the ebook is a hassle.

Received another order from Dr. Bob today. Everything was in good condition, packaged well, and there were even some extra goodies. Thanks Bob!

Dr.Bob - 11-4-2013 at 04:04

Folks,

Thanks to everyone who has ordered stuff lately, I have been just slammed busy with inquiries, so I have have not gotten back to an u2u or email, please don't hesitate to remind me, as I sometimes just get so many emails that I can lose track of older ones in the shuffle.

Also, PLEASE check your address in PAYPAL anytime that you order anything (from me or elsewhere). If the address there is wrong, change it BEFORE you place the order. According to the Paypal rules, the seller HAS TO use that address for the shipment, although it can be changed within Paypal if caught before shipped.

But once someone pays for something, I try to ship quickly and go to the post office most mornings at 9am. And once it is out of my hands, they will NOT let me have it back or change the address. I have had a surprising number of people use old addresses. I get the same problem with "One Click" orders in Amazon, with books going to students at their old dorm, to their parents address or the last apartment, so as a way to simplify your life, please change your address in every system like Paypal, Amazon, Ebay, etc when you move. Sorry to sound like someone's parent, but I don't read minds well.

Dr.Bob - 11-4-2013 at 07:14

I can't remember who was looking for spherical joint adapters a while back, but there is a whole set of them on Ebay for a low price so far, if anyone still wants them. about 10 of them for $10 currently. It is a great price, but still has 3 days left. If I had not sold most of my other spherical joints stuff already, I might bid on it, just to have the needed adapters. I don't know the seller or have any connection, just remember someone u2u'ing me looking for them, and can't figure how to search old u2us (I have >1000).

Here are some dewar flasks that I recently unpacked. There is a box of tall ones, and one of short form ones. There are snapshots and then links (hopefully they work now) to larger view. Those are higher resolution if you download you can see a lot of detail. The prices below are for one, if you are interested in more than one, I can make some deals.

The tall, wide ones are $75, the medium, wide ones are $60, the thin, tall ones are $50, the smaller 80mm dia ID x 65mm deep ($40). I have several of each size.

The short forms are ~170mm dia ID x 125mm deep ($70), 140mm dia ID x 70mm deep ($60) , 110mm dia ID x 70mm deep ($50), 90mm dia ID x 40mm deep ($45), 80mm dia ID x 65mm deep ($40), 80mm dia ID x 30mm deep ($40), 80mm dia ID x 25mm deep ($40), 70mm dia ID x 25mm deep ($35), 65mm dia ID x 25mm deep ($35). I also have some Redneck dewars, made of nested crystallization dishes with fiberglass or vermiculite between them, those are 190x170 mm OD/ID ($40), 150/125 ($25), 100/80 ($20).

Dr.Bob - 6-6-2013 at 18:57

I just finally gathered up what I have left of the thermometers, and took some photos for someone, so here they are:

If people want better photos of the glass therms, send me an email and I will send better ones. The glass ones are all Hg, I sold the non Hg ones, the main issue is shipping them, it can be pricy, as Fed Ex is the one who will take them legally. If people can get a few at once, or do a group purchase, the shipping becomes much better. The simple ones are $10-15 each, the 10/30 are $25, there are a few types and ranges.

Also, I have a few electronic thermometers, none have batteries currently, I don't know how well they work, and have not yet tested them in any way, but if someone wants to try one, I can make a good deal, once I get the working myself, the price goes up. Make me an offer. I also have some thermocouples for them, or I can sell them separately.

This batch is all yellow, or type "K", good for high temps, they are yellow usually, and go way above 300C in a linear fashion. I think I have some blue Type "T" ones also but have not yet found them. They would start at about $10, let me know what you are looking for. I cannot provide much technical data, but there is scads on the internet if you Google "thermocouple types".

AlChemicalLife - 10-6-2013 at 21:47

hey Dr, do you happen to have any 14/20 condensers preferably 200 mm or shorter, i also run with 24/40 so if there is anything else that is 24/40 or 14/20 i would like to take a look

Thank you sire

`Steven

Dr.Bob - 12-6-2013 at 05:27

I'll look, but I am running out of 14/20 stuff. I do think I still have a 14/20 coil reflux condenser left, looks like new, but not sure if I have any liebig type. I also have one or two odd 24/40 condensers left, need to get some photos of what is left, but not much. I still have lots of odd 24/40 pieces, like Clasien adapters, curved extensions, inlet adapters, and other more unique pieces. Many are pictured in the photos back earlier in the thread, but I will try to get some newer photos soon of those as well. I do have LOTS of 14/20 flasks left, mostly in smaller sizes, 5-50 ml, 1-3 necks, round, pear, recovery, etc. I'm happy to give quantity discounts on those.

You may have saw that I'm looking for a small reactor, since this glass come from a lab, I taught there might have a reactor.

Do you happen to have anything that reassemble a reactor?

Thanks

Dr.Bob - 12-6-2013 at 17:09

I might have one or two odd pieces, but I will have to look a bit to see if I have anything complete. I DO have a large fermentation type reactor, I think 20-30 L in size, with many ports, stir inlets, outlets, etc, but I have yet to even unpack it enough to get a good photo, and have no idea exactly what it for. I think I might have a few jacketed pieces, but will have to try to find the box of that type of stuff and look for it. These are the things I put aside at first as they were so large that I could not unpack them and had to idea how to sort them out and list them on my inventory. Now that much of the basic glassware is gone, I am trying to figure out some of he more complex stuff, but it takes longer than I had hoped to go through it, as it is hard to unpack and keep safe once not in a box. But I will keep a lookout for some reactors.

AlChemicalLife - 12-6-2013 at 21:47

Hey Dr,
if i could get a quote of the 14/20 flasks and coil condenser that would be much appreciated. iv also been looking for some hot plate stirrers, and some heating mantels if you have any.

Thanks

sargent1015 - 25-6-2013 at 10:28

Hey Dr. Bob, I am assuming the last list is fairly up to date. Do you have any vacuum aspirators or even pumps?

In addition, do you have a vacuum aspirator faucet adapter, or does anyone know of a cheap place to get these?

Sarge: Here's what I used for my kitchen faucet. I don't need it anymore as my lab sink faucet has the right threads.

sargent1015 - 25-6-2013 at 16:29

Hmmm I guess I could make one of those.... Just a simple adapter and an aerator?

Magpie - 25-6-2013 at 17:47

Quote: Originally posted by sargent1015

Yes.

I used a propane torch, flux, and solder. I'm assuming you've done this kind of soldering before. The only difficult part was that the solder didn't want to stick to the aerator very well. As I recall the aerator is chrome-plated brass. I suggest removing the chrome first, say with sandpaper, in the area to be joined. It should solder OK then I would think.

Well, successful soldering depends on the quality of the materials and the skill of the operator. Persistance is also important. I'm guessing that your chances of success are rather high. But I can't guarantee anything here.

I have a few water aspirators around somewhere. I have sold them for $5 apiece. The list is close, but I need to update it, once I catch up with a bunch of orders. I will be busy the next two weekends, so I won't get much free time to update things until mid-July.

I keep shipping stuff and then finding yet more stuff in boxes as I can get to them. Just found another box of hardware, mostly 3 prong clamps of all sizes, clamp holders, rings, and some other clamps. It was stinking heavy, and thus put as the bottom box in a large pile of boxes. Also found a few more 24/40 and 14/20 flasks, haven't had time to count them and update my list yet. And I found yet more Dewar flasks and condensers, still trying to get a list of them.

Thanks again to all of the people who have bought stuff and also thanks to the people for their patience, as sometimes I will get a number of emails or orders in one day, and I can only package and ship things a few days a week between my real jobs. But I have made a significant dent in the pile of boxes and can now fit my lawn mower in the garage again. Yea!

Furboffle - 27-6-2013 at 10:14

Do you have any 24/29 pieces? I have heard mixed reviews on whether 24/40 will still work with 24/29. I need a distillation adapter specifically. Also any stir/hot plates?

Oopsy_daisy - 27-6-2013 at 11:40

Second that, I would be very interested in some 24/29 glassware

Dr.Bob - 28-6-2013 at 07:15

I may have a few odd pieces of 24/29, mostly I think I have some flasks with those shorter joints. Let me look around and see what I can find. I am sure I have a few pieces, just don't remember exactly what.

mud - 28-6-2013 at 12:23

You found any D. Stark?

I'm requesting a pic of the condensers too please, when time permits.

[Edited on 28-6-2013 by mud]

DrSchnufflez - 28-6-2013 at 14:49

I'd be interested in these 100ml rbf (24/40), 250ml rbf (24/40), and a dean stark with stopcock (24/40) if you still have them

bob800 - 1-7-2013 at 11:30

Do you have any 19/22 condensers, 3-way adapters, or thermometer adapters?

Dr.Bob - 2-7-2013 at 11:09

I don;t think I have any condensers or 3 ways left in 19/22 but I can look, I might have a thermometer adapter. I do have a few small sized 19/22 rb flasks left, lots of 10, 15, and a handful of 25 ml & 50 ml, maybe a 100, not sure until I check.

I am out the next few days, but I will send emails to everyone that asked about stuff when I get back. Thanks for the patience.

Dr. Bob,

I sent you a message about any hotplate/stirrers. Also, are there any vacuum pumps or 24/40 pyrex boiling flasks left?

edit: got your message about no corning hotplates left. Any other brands?

[Edited on 12-7-2013 by malford]

Dr.Bob - 12-7-2013 at 07:26

I only have 24/40 rbfs left in small sizes, some 50 ml, 100 ml and a few 250 ml left (most of the 250 ml are scratched up a bit or well used).

I am mostly out of hotplates and stirplates, I have a few stirring only plates left, as well as one or two hot plates w/o stirring. I also have a few combo ones that are not working, if I can fix them I will sell them here. Once I get caught up with my current orders, I will try to post photos of the remaining equipment that I have. I have a lot of odd pieces left that I want to test or get photos of before I post them.

Any sep funnels?

Dr.Bob - 12-7-2013 at 18:51

Yes, they are listed in the spreadsheet, but I need to post a newer listing soon, now that I am back in town.

I have lots from 60 ml up to 250 ml, and then a few left bigger than that, most of which are either glass stopcock, scratched up, or odd in some way (eg, a 1L w/ a Teflon stopcock, but with a 29/42 joint at the bottom). Let me know what you are interested in, and I can tell you what I have left. I will also try to post what I have left for hotplates soon.

Sorry, just snagged a hotplate, so I'm good there.

Any sep funnels with 24/40 joints?

Also, any vacuum pumps?

Sorry, I would check out your xls, but the new computer I'm using doesn't have excel.

Dr.Bob - 30-7-2013 at 10:42

I don't have any sep funnels with 24/40 joints, but do have a 1L one with a 29/42 joint on the bottom, could maybe find an adapter for it. Might also have a non-equilibrated addition funnel left with a 24/40 joint. Don;t have any vac pumps. Still have small rbfs, clamps (3 prong and others), some 24/40 adapters and pieces, as well as lots of basic erlenmeyer flasks, grad cyl, and filter flasks and more. I can send you a text list of the items if you want.

mud - 1-8-2013 at 11:11

Malford - you can download for free Open Office or Libre Office on any Operating System and then open, view, or edit excel files...

Dr.Bob - Im interested in your broken stir/heat plate combos, the higher wattage ones at least.

Mr_Magnesium - 4-8-2013 at 19:36

Hello Dr Bob!

could you give us an update on what 24/40 pieces of equipment that you have left?

Was looking for some Erlenmeyer flasks, sep funnels and maybe a few reagent bottles

also what kind of shipping rate is it to Australia?

thanks

[Edited on 5-8-2013 by Mr_Magnesium]

TheChemiKid - 5-8-2013 at 06:04

Do you have a 1000mL 3 neck round bottom boiling flask or a vigreux column? Both preferably 24/40. Do you also have a friedrich condenser?

Do you also have a vacuum takeoff adapter and 1000mL heating mantle?

I am running out of most 24/40 glassware. I might have a 24/40 vacuum takeoff adapter left, but out of most larger round bottom flasks, most condensers and columns, and out of heating mantles bigger than 250 ml now.

I do have many sizes of Erlenmeyer flasks, sep funnels and maybe a few reagent bottles in some sizes left. International shipping went up this year, so for some items, like larger flasks, and reagent bottles, that are heavy, it become more than the item costs, and may not be practical.

I will try to post a new list soon, but I am going to be busy and mostly unavailable the next two weeks, so I will not be able to answer u2u's and emails quickly for a little while, so please be aware of that and patient with me. I am trying to finish shipping all current orders out but then will not take new ones for a week or so, until I am finished with another task. Thanks to everyone for their patience.

Bob

TheChemiKid - 5-8-2013 at 10:09

How much would you charge for a 24/40 105° vacuum takeoff adapter and how much for shipping to new jersey?
Also do you have 14/20 to 24/40 adapters?

Do you have any 2 or 3 neck 1000mL flasks?

Quote: Originally posted by Dr.Bob

c) Two enormously long west condensers. One is 600 mm ($35) the shorter is only 500 mm ($30). These were mixed in with columns that I was sorting through recently. They will not be trivial to ship, so please realize that the shipping may cost extra due to the length of these.

Do you still have either of these condensers?

do you have amber glass bottles?

Here is a somewhat updated list. I also just found a few more ring stands and 3 prong clamps, but have not yet counted them all. I have been working and traveling a lot extra lately, so I have not had a lot of time to work on this, but I hope to get back with a better inventory in Nov. as well as photos of the remaining 14/20 and 24/40 glassware. Thanks to everyone for being patient with my slow responses to messages lately.

Sorry if its already been mentioned, but how much is shipping to Australia? (Melbourne) Namely on the 144 8ml vials.

EDIT: Is it possible to get half of those? (72) Probably not, because of the repackaging, 42$ is a little steep (too expensive) for moi.

sep funnel 1000ml or bigger? - only have 1L one with a 29/42 joint at the bottom, Not sure what it is designed for, but would work fine for normal use as well. Like new with a Teflon stopcock. Similar example shown below:

bio mass flask? - Not sure what that is, but I do have some things that look like wide bottomed erlenmeyers with metal caps on top. One example is below, I have some them from 250 ml to 2000 ml, make me an offer. I think they are for fermentation or other biochemistry work. If that is not it, show me a link to one, and I might well have it. I still have lots of stuff I can't yet identify, just have not had time to post photos of it all.

steam distillation biomass flask

quantumchromodynamics - 18-1-2014 at 21:55

The flask above the boiling flask is the biomass flask. It lets steam enter the bottom and flow over the material and out the top before the condenser. I took me a long time to even find what the name of that weird flask. Addition funnel? Pressure equalizing addition funnel? I am happy to take that separation funnel off your hands. I need a decent sized circa 1L Erlenmeyer with a side arm. I also need a 2L RBF with 2 or 3 necks 24/40 (just asking

) to fit the heating mantle I am working on.

Similiar to a Kuderna Danish flask?

Funkerman23 - 21-1-2014 at 14:03

What you are looking for is a bit gimmicky but you can find the 'biomass' flask here and there. In the spring you might find more sellers as this stuff seem to be more popular then. DP glassblowing had some for a time( flask and the connencting adapter) and of course there are the boutique shops like heartmagic distiller ( Google for the link) . Failing everything else in this comment a standard Chromatography reservoir can be used and you will simply need to cope with the opening sizing. A local glassblower would be willing to make you one , possibly. I personally( as I own much of the other needed labware already) would buy from United glass Tech if Dr Bob Can't help. ebay shop link: http://www.ebay.com/itm/New-2000ml-Bio-flask-45-50-Top-24-40... but I don't know if they carry the one piece arm adapter at the moment( usually has the larger joint for the bio flask and leads to a more common joint size for the condenser) Avogadro's lab supply sells a glass kit with the bio flask but they call it an Alembic. Here's the bio flask only if you want to go with the Chinese option( buyer beware though) http://www.ebay.com/itm/2L-Chromatography-Reservoir-Flask-us... and Deschem's offering http://www.ebay.com/itm/2000ml-Chromatography-Reservoir-Flas...
