I found this thing, and I want to sell it on ebay, but the problem is I don't know what it is! It's picture is attached to this post. Please let me know what you think it is. Thanks    Andy

have you looked for a brand name? I think I see some marking on the front lower right corner- that might be it.  If you find one, just try googling it.

You probably shouldn't sell products that you have no clue what they are for, how to use them, or if they even work.

Uhh, thanks for the advice mitch, and no, that symbol may be a brand name's symbol, but it doesn't actually say anything. Thanks for the thought though. Anyone else have any ideas?

HAAKE (well, the picture is not pretty clear, perhaps I am misreading it) is a German surname, there are lots of firms with HAAKE in the name. Try google, perhaps you will be able to find something.

Judging from connectors and switches it looks like something built in sixties.

It's a Haake Buchler water/oilbath with cooling unit. looks like the temperature controller is missing so it's not much on it's own.

Also, if this helps, that symbol someone mentioned earlier says on it "Haake Gebruder Berlin", so I googled that and the first site contained this in it:

Rheological Measurements
A viscometer (Gebruder Haake, Model RV2, Berlin, Germany) with a rotating inner cylinder and a stationary outer cylinder (Model NV ST, Gebruder Haake, Berlin, Germany) was used for the viscosity measurements.

Does this mean it's a viscometer?  Sorry for my ignorance.

Its definitely an oil circulator and a very old model at that. The viscometer portion is not there in the photograph at least. Generally viscometers are used in characterisation of polymers(shear rate Vs viscosity etc).
