first time with vac

twistedj420 · Jan 14, 2014

Hi all, in the past I have made bho 3 times. each using the heat method to purge it. I recently picked up a vac chamber and a 3cfm 0.5pa single stage pump,now I am about to make a batch but I have herd a lot of different answers on how long t purg I for. Can any of you chime in with how long they purge for?

PA stands for Pascals and one standard atmosphere of 29.92" Hg equals 101325 pascals.

I like -29.5" Hg at 115F for making shatter, and it usually takes about 30/45 minutes to remove the butane, using thin film techniques.
