so i'm trying to gather all of the tools to do a BHO run ( I will probably do them a lot after i get it down) I've decided i want to purge with a vacuum chamber so I'm looking all over for a cheap option. I'm not totally against making something as long as it works well. i would prefer a store bought rig but i want to keep this as cheap as possible (seems like one of the few corners i can cut with this project) I was thinking there might be a way to rig a bag sealer to work, maybe put a chamber of some kind in the bag before sealing, idk, but I'm open to ideas. oh and with a store bought option it would be best if i could get it locally and not online. also if any one has detailed info or links for vac purging, numbers and stuff i would appreciate it. thank you in advance for the help
