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.

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.

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.

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

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.

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?

It is usually best forum ettiquette to add onto a post rather keep posting a bunch of short posts. Also, you are welcome to send me a u2u for simple requests, just click on my username and pick "send u2u" and I can answer your questions. I'll try to get back with the answers later tonight.

I am also trying to update my lists to re-post also.

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.

Here are some more photos of some more items I recently found. I have not been able to make the photos work yet via BBCode, but the links should work

<strong>Dr.Bob</strong>, you need to use the URL of the image file itself, like this:

Just thought I'd pop back in here to give a big thanks to Dr. Bob for the excellent glassware and awesome prices.

same situation with me:D, I had to go back and read what I asked for so I could puzzle out a couple of the surprises I recieved.

Another happy buyer


Got the package on Friday. Everything in great shape. Thanks!

What kind of tape did you use on that? That has to be the strongest stuff I have even seen!

Here are some more photos of recent finds as well as a new list. I have found a few more Dean Stark adapters in 24/40 w/ and w/o stopcocks, as well as some Freidrich condensers and other bits and pieces. I will try to keep posting more photos of the newer stuff. I also have found enough 14/20 parts to make a few dist kits, which I will post shortly. From left to right:

1) 14/22 Dist head (I'll find a a stopcock for it that fits) - $40
2) 14/20 Dist head (Dean Stark like one) - $40
3) 19/22 Dist head - $50
4) 14/20 Dewar condensers - $30, $30, $25 (bottom to top)
5) 24/40 Friedrich Condenser - $20
Please send me your email address if you want a better photo

hotplate stirrer? - I have a couple that I am fixing currently, once I make sure that they work, I will post photos

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


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 :o) to fit the heating mantle I am working on.

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...
