Best Bho Purge Without Vacuum

The best way to purge without a vacuum is to use a very accurate oven that can hold the temp at 170f 175f spread the bho as thin as possible on parchment paper after your initial waterbath purge to create as much surface area as possible.

Once the liquid is gone i move the pan to the oven and turn the temp on and off every 10 minutes for about an hour. Prior to blasting i preheat the pyrex dish in the oven lowest setting 170f. I don t have the spare cash right now to get a vacuum chamber so what other ways can i purge it i ve seen putting it in a oven after putting hot water under it and letting most of the butane boil off but i m not. Yes i m fairly new to the bho i ve read a lot of information about making and purging but i can t find any information on how to do small personal batched like 10 grams nothing big.

So after blasting the trim with butane and doing the water purge i was really lost. Anyways i basically stumbled upon alot of trim and decided to have him help me. I don t have a vacuum so i just use a low temp oven purge for my bho runs small scale 1g oil. Thus vacuum purging allows us to boil off the butane without damaging the quality of the bho.

He however didn t have any recommendations when it came to purging without one. Since you generally use butane for bho you should pay special attention to the green line. This allows the liquid butane to evaporate much faster. The graph below shows the boiling points of various solvents at different atmospheric pressures.

The simplest way to make bho shatter with a vacuum purge is detailed below. I have a friend that does bho all the time but always uses a vacuum purge.
