I have several 24/40 distillation adapters with inlets for ground glass joint thermometers. I also have more complex entire heads (with either a claisen head, condenser or vigreux column attached), also, mostly with joints for ground glass joint thermometers. But I do not have any thermometers for them available. (I think they got handled special due to mercury issues, do I never got them). I am still trying to find all of the distillation parts and get photos, but uploading photos is still slow for me. I am trying to find a better way to upload a group of photos in some order.

I completed a $250 order from Dr. Bob, it went smoothly, shipping was very fast (aided by the fact it came from NC, and I'm in VA)

This was possibly the easiest transaction I've ever made on the internet - I'll vouch for Dr.Bob any day.

~120$ - happy as a clam.

Another great deal with Dr. Bob...


I bought a big lot of media bottles from him and it was a pleasure doing business. We did a little bit of camel trading over numbers and price, but when it all shakes out, if you agree to take more stuff off his hands, he gives you a very reasonable unit price and tends to add in some extra. Kind of like that buddy you had in college who sold weed and always made sure it weighed heavy. (What can I say, that's high praise in biology circles):D

The whole deal took a few weeks to put together, but that was entirely my doing, as I was in no hurry. Once he got it all packed up and sent, it got here in one week. I had a couple losses to breakage, which is almost inevitable with that much glass, but the net result was still a very fair deal.

I did find some more 24/40 distillation head adapters now, with 24/40 joints at the top, bottom and side. I had run out and only had top thermometer joints left, but I have about 5 more now which I found.

The simple 24/40 dist. heads are $20 plus S/H (only a few $ for one).

There is a inventory and price list, abeit out of date, back a few posts. I need to update it and repost it, but it has most of the glassware listed. I still have lots of dist. equipment, 3 necked flasks of many sizes, and scads of 14/20 glassware. My 24/40 glassware is starting to run out of a few sizes, but I have lots of 50 ml RBFs, a few 100 and 250 ml flasks, and then some larger ones left. And some dist. heads, claisens, condensers, etc left.

Plus I have some beakers, a fair number of new and used erlenmeyers, lots of filter flasks of all sizes, and much, much more.

I bought from Bob through paypal and everything came, without a single piece broken. Would definitely recommend, as not only are the prices great, but he's a nice guy!

Yes, I have the following:

Adapter, Vacuum Take-off, 105°, curved 24/40
Claisen Adapter, 24/40
Adapter, Distillation, 24/40 Joint Size, Side Inner Joint At 75°
graham condenser 24/40 joints

Please send me a note with your city and state and I can give you exact shipping costs, but this would roughly be $90 to most places in the US.

Bob

I still have boxes of glassware. I am slowly running out of a few larger sized items (like 4 L beakers, and 1 L 24/40 RBFs), but have lots of most items still. I'll upload a newer spreadsheet inventory soon.

Here is a more current list of glassware and prices. All items are subject to prior sale, but if you are interested something, just let me know and I can verify that I still have it, as well as tell you what the condition is and about what it would cost to ship. A list if fine, either as an email or even just add a column to the spreadsheet and put how many of something that you want for each item. Whatever works is fine.

Thanks to all of the people who have bought items so far, it has helped me clear out a part of my garage as well as provided some income for my friend.

Mainly the vacuum take off and the thermometer holder/side arm thing. I mean the piece you'd put in the top of your RB flask to hold thermometer and feed to your condenser. Or just a thermometer holder. All in 24/40.

What about plain thermometers?

THx for your time.
