Currently using a Birko white mineral oil product, problem we have is after a few months it degrades and it starts smoking a little bit just doing regular solvent recovery, and smokes a lot during decarb at ~115-120C. Its bad enough we plan to decarb at night so nobody needs to be in the lab when the temps are brought up and the smoking starts, and have a pretty good idea of when decarb is done timewise so nobody has to stay in the lab to monitor things.
I want to change fluids once and not have to deal with this again, buy once cry once and all that.
Wondering what everybody is using for thermal fluid, especially those of you who are doing decarb and the associated higher temps in your rotovaps. A couple recommendations I’ve received have been DQ’ed after reading that in open bath applications these fluids are damaging to lung tissue or other nasties.
