Title: [Mink] Jacketing for your distilling head...
Post by: alchemy_bee on April 22, 2002, 03:06:00 AM

SWIM spent a hundred on a nice vacuum jacketed column for his vacuum distillation setup - splurg alright!, but hey the best for the best...

Does a several hundred dollar vacuum jacketed distilling head like this have any practical gain in distilling efficiancy? Better yet has anyone ever used somthing like this even?

I'll bet it can bee the difference between some and none in your recieving flask when distilling some really high boiling point compounds

A vacuum jacketed head is nice, but if you don't want to spend the money you can use glass wool to insulate the still head (will stand lots of heat, >300C). Also fleece works really well if the compound is <150C... and cotton comfortably goes to about 200C...
