^^ person above me is half right..
go to smoke shops.. buy vector..
pure n-butane is very very expensive.
butane sold in cans is 30% propane
not to worry propane and butane are only an atom off on a molecular level.
but yeah.. local head shop..
go read my tek in the concentrate thread.. guranteed best results
You don't need all that - you can build a vac purge much cheaper or even use a mityvac brake bleeder for personal size runs. My power vac was like $150 & I built a chamber out of a mason jar for next to nothing. I use a $14 heating pad & can purge a few g in a few short hours.I hear there's a brand PURETAIN that is 9x. Google it. Says 99.998% pure on the blue and white can. I was going to get some but I can't figure out how to evap the stuff without a nineteen hundred dollar vacuum oven. I'm not spending that much and I don't trust anything else to get the toxic residue out. Guess I'll just keep screening trim leaves for hash for now. Love to try the butane thing though, sounds like a project for the future.
Aren't carbon dioxide and carbon monoxide only off by an atom on a molecular level? Just sayin'. No freaking wonder so many people are blowing up rooms and starting fires. Lol.
