Acquired large Research Lab lot - help me identify items? Also, taking requests for glassware.


Hi everyone,

My partner and I recently acquired a very large lot of glassware and supplies from a biochemical research lab in the Seattle area. I'm just beginning the process of listing items for sale on eBay, but I wanted to open up the channels for requests of items here too (assuming that is OK on this board). I have lots of parts from Rotavaps, at least three dual bank vacuum manifolds, etc etc. 5L chemglass airfree solvent still, really an epic haul. Virtually anything, some things brand new, some things crusted with unknown inorganics :D

I'll start posting photos soon of "what the heck is this?"

Thanks!

-jaid

Assuming that there are no legal problems in doing so, sure. It would be somewhat expensive on shipping though, I'd imagine. I'd prefer to do everything through ebay or at least paypal so I can keep a tax record, since we're selling through a business.

I'm looking for a "reservoir flask" >500mL
A dean stark trap
A 2-3 necked 24/40 Round-boiling-flask
A heating mantle to match the RBF
And, an addition funnel

I'll look through the boxes for the Dean-Stark apparatus. I think I saw at least one.

What size RBF and what size addition funnel? Do you need a controller, etc for the mantle?

Reservoir flask like this:


Do you want the reservoir flask in 24/40?

USA?

Name your prices.

Any idea what to call these pieces?



This one looks like a vacuum or pressure addition syringe for airfree, and it has a stop screw to set the volume, but I have no idea what it would be called.



I don't even know if these are assembled correctly or how you might want to use them.



?



This one is Ace Glass. Here's detail of the valve. The ends are 24/40.

Looks like you haven't uploaded your pictures. You can't ask the browser (in my case over the Atlantic) to look up an adress on your computer. To display them online, you have to upload them to an image hosting service. Or you can just upload them as attachments when posting. Just click "Browse" by the Attachment option, select your image(s) and post the reply. I'd be happy to help you if I can recognize the glassware myself.

HAHA. Thanks. Not everyone has the same entries in /etc/hosts as I have.

Pretty pathetic for a UNIX guy :(

Don't worry, we all have one of "those moments" once in a while... :D

Second picture from the top with the red plastic connectors: The bent thing on the right side is a short-path distillation apparatus. Used to distill high boiling compunds or when you're dealing with small amounts of compound. On the left is a two-neck round-bottomed flask and a thermometer/tube adapter.

The plastic connectors have screw threads right? Those are somewhat rare.

Third one looks like a bubbler (although I can't imagine why you'd want a graduated one). Does it have an internal tube that protrudes to the bottom?

Last one is stopcock/valve adapter (I can't recall what you'd normally call one of those). The black plastic valve allows for more precise control of flow compared to traditional stopcocks. These ones are commonly called "Rotaflo" stopcocks, but I think that's a trademark. Ace probably has their own name for these.

Thanks. That's a start. I'll keep posting as long as it's entertaining for everyone. It is certainly useful to me.

What are the joint sizes in the second picture....I really like the look of that piece. The short path distillation adapter, that is. Asking price?

I'm betting my socks that they are 24/40 ;) I've never understood why you americans would want to screw around with joints larger than your flasks, though..!

They're all threaded 24/40. Let me see how much more glass I have with the same fittings, etc. You'd need more threaded bits to make any use of it, I'd imagine. You want *just* the distillation head? Make me an offer USD.

I have tons of Rotovap adapters like so:



Think anyone would want them? How to name them for eBay?

Also a liquid-liquid extractor you could knock a guy out with. Not sure where the dispersion tube and condenser are yet, but I'm sure they're in a box here. Estimated value? Looks like 2L:

US dime is ~17mm in diameter, for comparison.

I'm really hoping someone wants the solvent still. It looks basically unused, but I was mistaken, it's only 2500mL.

Do you have it listed on ebay yet or have any images to show us?


I'm also very interested in seeing what rotavapor parts you have. Could you snap a pic of the lot?

I only have, so far as I know, multiples of what I showed, and >20 bump flasks of different sizes. I literally don't have the space to unpack everything at once so it's hard to say exactly. I *may* have the special Buchi condensers, but I have no mechanical parts of any kind.

I haven't listed the solvent head but I will show you photos shortly.

Thanks.

This is an adjustable volume repeating liquid dispenser. You set it to a volume and every time you lift the piston and push down, it dispenses that volume of liquid.

Note the direction of the check valves. The syringe is filled from the inlet at the bottom, and dispenses through the outlet at the side.

Name your prices.

RBF - 1L, addition = 250mL , no controller - just mantle, reservoir yes - 24/40. USA.

Once you confirm all of these I'll make an offer.

It would take literally 900+ square feet to lay it all out, so I don't think I can. Once I sort out some secure shelving I will start posting pictures of everything, now that you say.

For now, here's the 2500mL Chemglass solvent head.

I do have the makings for that but I'm not ready to sell smaller pieces just yet. I need to get the multi-hundred-dollar stuff out of the way first to get some money back on this huge lot. Once I'm more organized I'd be happy to start selling single RBF's and distillation kits and the like.
