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.

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.

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.

Bob

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?

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.

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.

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.

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 :/

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..

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.

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 :).

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.

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.

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).
