Yes, once the resin is viscous you can take it inside.after all the butane evaporates in warm water outside can i take it indoors for further processing? since i take every precaution that i can think of when i make BHO, i want use a home made vacuum pump and do that indoors casually. scrap into a glass jar then hot glue those big medicine syringes (ones without needle ofc) to the lid. so it will make a vacuum when the jar is sealed and the plungers are pulled. i dont see a hazard appling heat to it while its under a vacuum. i could get a balloon filled with argon gas from my friend and try to make the gas in the bottle as inert as possible. shouldnt be dangerous to smoke afterwards as we breathe 1% of that shit. i need criticism.
Your homemade vac chamber isn't exactly safe, but if you are hand pumping to achieve vac then you should be okay.
Don't worry about argon gas, not sure where you going with that one. Just let your erl purge man, if its not warm enough for the bubbles to escape, it ain't really purging.
