So I have been running small batches in a cut down SSTB. I get 5 to 5.5 grams of high grade nugs in it and get about a gram back after thin film purging the hell out of it. I want to try to winterize, can I do it on this small scale? Would two shot glasses work for this, followed by another extended low heat purge to evap away the everclear? I know I need to get a vacuum, but that is not in the financial plans until i start running larger batches. Any advice and/or criticism is greatly appreciated. TIA!
