i have a hand vacuum that i can get to -27hg or psi i really don't know the measurements. i just know its pretty much impossible to get to -30. Just wondering if thats enough strength to purge the butane out and make shatter. I purge out of a mason jar thats in a pyrex of water that is being heated by a griddle set at 120…any advice or input would be much appreciated. thank you RIU community.
