That last one is particularly weird. Some kind of jacketed reaction vessel. But I can't imagine what the connections are. The orientation of the
ground joints seems strange. Maybe rotate 90° to the left. Powder input on the side and then stoppered. Addition of liquid and temperature
measurement via the ground joints. Excess solvent or liquid product drains through stopcock. But these are just guesses.
First one looks like a gas drying tube. Bubble chlorine etc through H2SO4. Setup allows for system to be drained without disassembly. But I am not
sure what the spherical bulb is for.
Middle one is a kind of jacketed beaker. But the wide ground glass opening is a bit interesting. Maybe just a lid. Maybe designed to work with
another equally strange piece of glassware.

Visited an estate sale this morning. Seen this broken item
It looks like a plate still, with 1 ground glass joint at the base and an open top
Bottom plate has a glass mesh, middle and top plates are bubblers.
Not sure if its just a gas scrubber or if they went all out making a bong

Very odd piece
Don’t know exactly what this is. I got it in a lot for a Soxhlet extractor. It looks like a mixing cylinder but it has a make joint.

That is the bottom of a gas washing tube. The tops get broken easily, and have a fritted tube (and an outlet tube) on a female jointed top. You
would fill the part shown with some liquid or solid to wash the gas in.

Here is a similar gas washing bottle base:

*edit*
The male joint kind of threw me a bit too.

Don't know what it's intended to be, but I would sure use it as a drying tube.

Is this a Kjeldahl bulb or a Chromotography Reservoir? Or both

It is a bump trap, (old design, before rotovaps became commonplace)
Normally fitted above a boiling pot to prevent splashes caused by bumping from reaching the condenser.

it larger or something but i cant find much else
Any idea?

Very interesting looking piece of kit! Could it be used for the separation of aqueous and non-aqueous liquids?

Looks like someone's brilliant idea
that didn't actually work.
OR maybe just a lamp work test/practice piece?

Also could be used as a fermentation tube.

It's not glassware but I hope that is OK.
What is the extra stuff on this vacuum pump?
on ebay here:

My guess is that the small gray cylinder near the pump input is a vacuum switch. When the vacuum gets down to a low enough value it switches on the
assembly on the left end.
The assembly on the left end with the fins is probably a diffusion pump, a very small one.
The diffusion pump is air cooled. On top of the diffusion pump is maybe a butterfly valve that is controlled by the lever with the black ball handle.
I think there is some sort of plug or reducer on the diffusion pump inlet.

Thanks for reply.
I though the piece with the air heat sink might be a diffusion pump but though it was too small!
The electrical boxes say forevac. and highvac so you are correct.

Inherited a bunch of glassware!
Can't figure this one out. Cross between a few things I can think of, but doesn't work in those roles.

Here's another one. Obviously an air lock, but for something needing careful temp control via the jacket. The inlet from the top goes through a frit
and then a tiny glass triangle ensures any drip falls straight. Odd access to the sumps via the barbed connectors. Lastly, the base doesn't have any
precision fitting to go on a reaction chamber. Maybe o-rings? Any clue what chemistry this might be used for?

Got this lamp, labeled "Phillips M13", 0,5 ohm and I suspect it might be a spektral lamp producing only a certain part of the lights spectrum.
Could not find anything on the net, what is strange, so I ask here:
What kind of lamp for what spectrum and what application is this?
thx

I have a bunch of these things, they have a 19/22 joint, then 4 inches of wavy the end diameter is about 5/8" or 17 mm OD. The overall length is 5".
Any ideas of what it is useful for? I'd love to know what they are and even better find someone who has a use for them.
