Does anyone know what this is used for?
I found this on Ebay and it's a rather odd and complicated piece of glassware. I was just wondering what you'd use it for?

I can't see the photos on my work computer as they are "censored". But a custom distillation head with dual condensors would describe a whole host of
variable reflux heads, as the reflux column has cooling as does the side shaft that redistributes the condensate.

I looked at the ebay listing too. It is not a variable reflux head because the stopcocks aren't there. I don't understand the joint in the middle of
the main riser tube. I have a variable reflux, vacuum head in 14/x size. This is quite different. It's a custom made setup made to capture volatile
components. But why the gas trap in the coolant line above the larger condenser? Why the oblique, upward pointed condenser? Why the second (higher)
upright next to the thermometer tube? Maybe it was made in the glass shop and dumped because it didn't work? Or maybe it was designed and used for a
special project...?? It appears to have been made to use different coolants than water (?)
Here's a WAG: maybe it was made to run an exothermic gas phase reaction....!??!

I have no idea what happened the first time I tried to post the picture. I was using a library computer, and it had a different operating system. When
I got home and downloaded the image that I had posted....
Anyway, sorry to anyone (nine people apparently) that downloaded the broken image.

My turn. This is a modified buret, with a two way stopcock on the bottom and some sort of container on the top, with ball/socket joints on the top
and both outlets. ANy guess what this was modified for? Gas generation or electrochemistry?
Here are some photos:

I think that's an automatic burette.

The first piece must be a variable reflux head probably with a (missing) special stopcock (or equivalent) that goes through the long tube before the
split to the condensers.
This just in: 95,5 % of the world population lives outside the USA

ID a piece of glassware please (and practical use)
I bought this piece of glassware from a guy on my campus about a year ago and he said it was a custom made piece (he didn't know what it was called or
used for either).
I know what the two pieces are that are fused together, but I am not really understanding what it is used for in a given experiment. I would also like
to know the name of it, if there is one. I figure some members might be able to ID it for me and explain the general, desired function.

Dr. Bob - as unionised said, it's an automatic burette - it can be rapidily refilled through the bottom, extra connection, to a precise level, as set
by the take-off at the top. Thus, you can do lots of samples with minimal time
You only need to read the final volume.

Thanks, I thought I had seen everything, but I have never seen an auto-buret like this, but that makes perfect sense. Thanks to unionized and jwpa17
for their input. I'll have to find some of the other stuff I have that I can't figure out what it is and post more of it. Thanks. The more I
learn, the less that I seem to know.

the condenser condenser thing
organicchemist25 - that is truly strange, it is a condenser condenser, a combo fractional condenser with a reflux condenser in parallel. Maybe for
increasing the number of reflux events per loop? Cool looking though...
