Jeffa42 Posted May 14, 2018 Share Posted May 14, 2018 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.

S101 Posted May 21, 2018 Share Posted May 21, 2018 Search ebay for "laboratory water bath". Make sure it is a model that will chill your sample to 60 degrees F. Link to comment Share on other sites More sharing options...
nabtastic Posted May 23, 2018 Share Posted May 23, 2018 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. Link to comment Share on other sites More sharing options...

Did you find something you'd recommend? Thanks! ~cathy Link to comment Share on other sites More sharing options...
John Bassett Posted December 24, 2019 Share Posted December 24, 2019 95% of the water baths on eBay are heated only. It has to be cold in the lab to work. The water baths that cool are all pricey. Link to comment Share on other sites More sharing options...

FijiSpirits Posted December 25, 2019 Share Posted December 25, 2019 I’ve been using a beaker of ice water to chill the measuring flask and pycnometer. It sounds cheesy but if you go too low in temp just warm it in you hand and swirl it around to mix until temp stabilizes. Then measure real quick before condensation occurs At small volumes it doesn’t take much time. Id love to find a source of a cheap chiller tho. I could also use it for cooling water on the lab still and for vacuum distillations. I had thought about using one of those electronic chiller coils and just pumping coolant (alcohol/water) or water thru it to make my own setup. A power supply and 570 watt chiller runs around $300usd delivered from AliExpress. Then just use a Coleman cooler for a reservoir and a small pump and temperature controller for the chiller and you are golden. Link to comment Share on other sites More sharing options...
