My question is can you use a bag vacuum sealer to purge the butane if I put the oil between 2 pieces of parchment paper? Everyhting I see uses a jar or something where the oil isnt going to be squished. Thanks for your time...
Of course you could. I'd suggest using something with some rigidity though. I've got a small jar, I've attached a picture, that would work great. What I'd personally do is drill a few holes in the lid so the vacuum bag wouldn't suck down into the jar and squish your BHO. The small jar should be able to withstand the pressure, but I'd give it a test go first. You may have to place something across the top of the lid, so the bag doesn't seal against any holes that were drilled. I'm not sure if it's necessary, but it's something to keep in mind.
