Progress on vacuum chamber build - helium leak detection, custom flanges

if u dont know who this guy is then ur missing out. he not cannabis specific but hes built supercritical co2 extraction, high vaccum setups, electron microscope and spectrophotometer in his garage. so if u want get a could understanding of the mechanics of these kinds of systems this is a good reference.
