Vacuum evaporation is way safer than boiling solvents off, as well as resulting in a cleaner end product. This is the way we isolated alkaloids for cancer research experiments in the 80's. You are on to something good there!
HavaTok Reviewed by HavaTok on . Vacuum and fractional distillation I just love it when a plan comes together! Here is my new rig for vacuum and fractional distillation undergoing shakedown boiling water this morning. I followed by removing the hexane from an hops oil extraction and then washing it in ethanol and vacuum distilling that off to leave an absolute. I also picked up an Alhin condensor and a soxhlet, for refluxing, isomerizing, and soxhlet extractions from hash. Tomorrow I will try it on a cannabis oil run. Hee, hee, hee, snicker, Rating: 5
