Cold Water Bath

Recommended Posts

Before anyone asks, yes, I am searched the forum.  I am just looking to see if anyone uses a cold water bath for proofing with obscuration, or solids in their distillate.  Anyone have any recommendations about where you can get one at a reasonable price?  I've already got a small bench still to run this stuff on, but for accuracy, I would rather just have the temps always constant.  Any advice will be appreciated.

Search ebay for "laboratory water bath". Make sure it is a model that will chill your sample to 60 degrees F.

Affordable is relative.  We went with the one our Anton Paar rep suggested - it was around $3-4k (purchased a few years ago).  Any water bath that can fit your flask will work. You won't need anything fancy as long as the liquid in the bath covers the liquid in your flask and the temperature is accurate.  Our brand is PolyScience but it's definitely overkill for our purposes.
