Swede Posted February 24, 2009 Posted February 24, 2009 I couldn't resist an assortment of surplus labware, some used, most new. Two of them are very curious. The first (probably easiest) looks to be some sort of condenser for collecting sublimated solids or liquid materials. It has a jacket surrounding an inner chamber, and some sort of proprietary interface:http://www.5bears.com/chem1/mys04.jpg This next piece is beautifully constructed of plexiglass. I believe it to be some part of an automatic titration device, but I really don't have a clue. There is a valved port on top, several sealed micro-ports around the perimeter, and one heavier, angled port, stoppered with silicone. On top are two heavy ports that contain some sort of metallic filter element. There is an o-ring on the outside; it obviously fits into another tube. Any Guesses? http://www.5bears.com/chem1/mys01.jpg http://www.5bears.com/chem1/mys02.jpg http://www.5bears.com/chem1/mys03.jpg
Miech Posted February 24, 2009 Posted February 24, 2009 I have no clue what the second thing is used for, but I'd guess the valve is to regulate a continously stream of (inert) gas to stir up fluid inside the 'thing'. That would also explain the two filters on top, they would let the gas escape without much spillage of fluid from bubbling and such. It looks like there is 'Acros' written on top of it, so if you really want to know what it is you could try to mail 'em.
Mumbles Posted February 25, 2009 Posted February 25, 2009 At first glance I thought the second item looked a bit like a cyclic voltimetry apparatus. The top I don't know. does the jacket come apart? I can't decide if the coolant should flow through the nipples on the side or sit on the top resevoir.
FrankRizzo Posted February 25, 2009 Posted February 25, 2009 LOL....I was wondering the same thing, Mumbles. I wonder if it isn't a self-contained water bath.
Swede Posted February 25, 2009 Author Posted February 25, 2009 (edited) On item 1, the glass is monolithic, and the inner collection chamber cannot be removed. I was thinking cold water through the jacket to condense, but it would make a dandy heater as well, if you can figure out how to circulate boiling water continuously through the jacket. I've got two of them, just one of the second object, which is so beautifully made I'm tempted to put it on a bookshelf along with a few other chem curios. The lettering is "Aerosol" and I'm not sure if that's a brand name, or a description of what it does. Both were obviously part of a larger system, perhaps the same one. Thanks for the comments. I like mysteries like this. Edited February 25, 2009 by Swede
Miech Posted February 25, 2009 Posted February 25, 2009 Hmm, the second thing could be an aerosol saturator. I'm not sure, but I wouldn't know what else it would be.
Ignes Posted February 25, 2009 Posted February 25, 2009 Item 1 looks like an item we use in the lab to dry gas. Only both nipples are on the same height as the upper nipple, in our case. The cavity is filled with dry-ice and acetone.

The cavity is filled with dry-ice and acetone. Interesting! I bet it would still work if the gas is introduced into the lower nipple, and exhausted from the upper. In that format (acetone + dry ice) it would pull just about ANY liquid out of the gas stream and would make a neat little micro-condenser.
