This one looks really odd, and cool too.
Stab in the dark: wierd distillation gizmo.
Condenser goes on top.
Collection flask goes bottom Left.
Boiling flask goes bottom right.
Vapour enters the central column via the middle right hand pipe.
Condensed liquid collects at the bottom of the central column until it overflows via the bottom pipe into the collection flask
The left hand pipe serves as pressure equalisation for the collection flask.
If the collection flask is full, liquid can overflow back into the boiling flask by the bottom right hand pipe.
The top right hand pipe is there in case it all goes fubar with airlocks and the liquid somehow fills the central column.

Looks like a reversible oil separator to me. One way around it collects lighter than water oils from steam distillation.
Reverse the collection and boiling flasks and it collects heavier than water oils from steam distillations.
And it could obviously do the same for any other distillation with a 2 component distillate.
This is just what it looks like to me. Never seen one before though. But it seems to be a simple and elegant way to achieve those ends without a bunch
of external tubing or valves.

Same here. Natural products make great starting materials for some of the most interesting reactions.

Agreed. I have an enormous camphor-Laurel tree outside my house. (Actually, the streets are lined with them. They look great but have very invasive
root systems.)
Anyway, on my list of things to do is a camphor extraction. Now there's an excuse to buy a soxhlet.

I can make any glassware that takes your fancy. The customised odd looking stuff is always more fun.

Looks great chemetix.
Details of your prices and shipping policy would be nice. Maybe you could write yourself a little ad in synthsource. See my sig for details.
(The aussies may as well take over the site.  )

Thanks J_sum. I generally do professional work where the customer asks for a quote and raises a P.O. for the job. I hadn't really thought about the
hobby market until now.
For now I'm happy to take inquiries and I'll see what I can do to meet a budget. I'll look into synthsource, (mind if I U2U you J_sum with some
questions?)
P.S. my site is being rebuilt ATM and there a few things missing, the tricky e-commerce stuff is harder to set up so it's basics for the moment, it's
best to send an e-mail with an inquiry and I'll get back to you for the time being. (I miss the simplicity if a yellow pages ad and a phone; whoever
said the information age would make life easier-lied)

Aquired some glassware and an old rotavapor-R
Hi all this is my first post on this forum so if this isn't in the right place please move it
I recently aquired a Buchi Rotavapor-R and with is came an odd piece of glassware and wondered if anyone could help me identify it. I dont think it
belongs to the Rotovap but I could be wrong?
The tube on the left has graduation marks to 25cm3
The tube on the right has a very thin tube running up the centre
If you would like more detailed pics let me know
Thanks for your time
H

Looks kinda like one of those things for getting liquids out of storage bottles without exposing them to atmospheric contamination.
(Just what you need to keep your SO3/ dimethylformamide complex from turning too orange on you before you can use it to make a certain amide for the
next Dead show.)

Ah that makes sense I did come with a bulb for applying pressure so it could work for both purposes will test it at some point with some water.
Seems like one of types things which would be a nightmare to clean ha ha
Thank you

They are a nightmare to clean. I have one (pictured earlier in this thread I believe) and it's been sitting around dirty for months now since the last
time I used it. They're cool, but regular burettes are actually less of a pain in the ass I think.

It is intended to sit in a bottle of standardised solution ready for whenever the need for titration arises. As such it is not meant to be cleaned on
a regular basis, rather dedicated to a single titrant.

10 ml automatic burettes are a huge pain in the neck to not just clean, but operate. If your liquid is more viscous than water, and you pump it too
quick in the burette cylinder, very often it will get stuck midway due to capillarity. You will have to keep the burette valve open and keep refilling
the burette cylinder until the solution level is high enough that it will push the air downwards, though I've had cases when even that didn't work,
the liquid would sometimes drain around the air bubble, and I had to completely empty it and restart all over again until I finally managed to fill it
properly, which sometimes would take like 10 minutes when it should only take 1 minute. Any automatic burette with a volume larger than 10 ml is much
easier to maintain and use, even when they clog.

This was fun to watch. But I haven't got a clue what it is.

And these!!! There's some weird stuff there. And maybe 10% is obvious what it is for.

My suspicion is that the first one is a custom steam distillation flask, it has an integrated distillation flask with the water boiling flask.
The other items in the second youtube vid are exam pieces for glass blowers. You get given a drawing which contain elements of glass blowing skills
and become progressively harder to do in a given time as the course progresses.

Not a filter as such: it's an air sampling tube

Firstly the wooden thing from a couple of posts back is a crucible die, for stamping out foil crucibles.
This thing here is the dandest thing. It is finely cut black stone, very heavy and has two electrical fittings to it where it would appear something
sits. Never seen a bit of kit made from stone and

If anyone here wants their own drying pistol, I have a few of these. I don't know if I have the other piece (tube with a male joint to put the
drying agent into), but I can look around.
