Thin film purge in a dry environment with enough heat to get all solvents and moisture out.
The chart is quite wrong on several entries. Including THC like several others as I've pointed out and laughed at here before, but the one that jumped out at me was b-sitosterol, so I looked it up. It does not boil at 134C since according to the Merck Index it doesn't even melt until 140C.
So, I would suggest reference material written by people with half a clue.
Boiling points under reduced pressure are never published in any way without the pressure notation, except for/by stoners.
So is the final consensus that sharding is due to impurities and shard cleaned will turn to oil or no?
My vacuum allows distillation at under 100.
No, thc comes over under 100c 25 micron vacuum is no joke
