RotoVap SOP needed for thca

Need some help with parameter settings on my RotoVap. Specifically to preserve thca while removing ethanol. What is the best bath temp, vacuum depth (torr) and duration in roto? Any help is appreciated :metal:t2:

As deep as you can go on a diaphragm pump, and the temperature as low as is acceptable. Probably 40C or less on the water bath and you should be good.

I’ll do 37C if I’m in a hurry. 30C if I’m not. 27C if I’m aiming for competition grade :wink:

Edit: tune-able leak on vac pump so as not to overwhelm the chiller (which is the weak link in my setup).
