Has anyone ever come across a 24/40 thermometer adapter with o-ring that can fit a 10 mm probe? It seems most 24/40 max out at around 5-7 mm. I found
this https://www.wilmad-labglass.com/Products/LG-1451-306/ but $50 is a bit steep.

I have a distillation adaptor that has space for a 10mm thermometer. I bought it from deschem. One of those with a stopper where the condenser might
work, depending on what you're doing. I'll get the link to it if you want
Nuclear physics is neat. It's a shame it's so regulated...
Now that I think about it, that's probably a good thing. Still annoying though.

If it's not too much trouble can you find the link? I have a deschem 24/40 thermometer adapter but it maxes out at around 7.40 mm.

I have at least two types of 24/40 adapters which should work with 10 mm tubes or trherms. I would sell them for $15. One is an Ace brand therm
adapter but with a 10 mm #11 inlet adapter, the other is an all PTFE one with a red GL type 10 mm adapter on top. Let me know if you are
interested, postage would be about $3-4 in the US.

The listing I bought it from seems to now be down (not surprising given I bought it over a year ago), I'll see if its been listed again under a
different link

This looks like it *might* be it, it looks the same and is from the same seller, but it is a different listing, so it might not be. It does look
pretty much identical to the listing I bought it from though.

Most thermometer adapters are designed to handle 5-6 mm and that is about it, the hole might be 7mm, but that would be hard to seal well. Ace sells
many adapters for various diameters, including one for 10-11 mm, which is also the diam of most glass stir shafts (not counting the cheap ones from
China).

Hey, yall.
Is this a chromatography column with hooks on top for some reason, or is this some kind of vacuum adapter or filtration adapter?

Some call it "koń" where I live, so a horse. But I doubt that applies to other countries!

I would guess that it is a way to hold down a gas inlet (often an inlet with a variable stopcock release to control the pressure on the flash column.)
so it does not blow off under pressure. But you rarely see them on a column with a vacuum adapter, as you normally use only pressure or vacuum.
Might be meant to allow some sort of liquid feed adapter to be held to the top while vacuum is applied. Not sure of any specific name.

Anyone know what this thingy is?
It looks like it's maybe a bubbler (or scrubber) with a suck back trap all in one piece of glassware? Perhaps you just put the liquid in the right
part which can act as a bubbler or even scrubber, and if the reaction causes some negative pressure (suck back), the liquid would go into the part on
the left as opposed to into the reaction vessel, then when the reaction starts generating pressure again, the liquid in the left part will get pushed
back into the right part, maybe? What do you think?
P.S. I found that photo while scrolling through this amazing chemistry photo portfolio, which I found in someones signature here on SM. If any of you haven't seen that page (or the homepage of the same site), I definitely recommend spending some time scrolling through it. I had no idea chemistry could be so insanely gorgeous.

These pieces and others like it were donated to my classroom. I've never seen glassware that connects together this way, and I'm hoping someone can
tell me what this connection style is called so I can research it.

Well there are two on ebay...
The last time I saw anything like it the caption said "The glassblower had hiccups".

Well I'd buy one as long as it makes that sound.
Besides, it might come in handy for the co-polymerization of amino-acid residues and carbohydrate molecules, both containing ionic groups.
It should be perfectly simple if I can gt the heavy hydrogen, and maybe a bit of radioactive thorium.

Electokinetic,
They appear to be reservoirs for chromatography columns to me. You can screw them to the top of a colum to hold solvent, then either use gravity or
air pressure to move the solvent through the column.

Hi there,
Came across this strange piece when looking for glassware on my local auction site. Could anyone identify this mysterious part?
Cheers!

Crucible with a perforated base
I have a small ceramic crucible with a perforated base. Maybe it is designed to heat/react something until a molten phase can exit the base? Ant
thoughts? Thanks AB
