Anyone have any tricks or tips or is it even possible to run a rotovap (5l) in 40-45*f ambient temps? If so, what are you putting over the water bath and flask to help keep temps where there supposed to be?
Would there be any issues of the etoh condensing before its hitting the condenser?
I’d rather not do a run in a spare bedroom with a fan blowing air outside.
I was gonna say…the system under enough vacuum should be fine. If anything, colder ambient temps makes the condenser not have to work as hard and will help condense solvent on the cold glass as well. This is a benefit, not a hinderance. Maybe consider using white mineral oil in your bath.
Borosilicate glass can handle the temp differences, it is built for it. Hell, its continually below freezing outside here right now. I had a fantasy of filling a tank outside with glycol, on the north face of a building where the winter sun never shines, and pumping it in and out for a continual subzero bath.
