Thanks i guess we'll try it out. How much bubbling should occur when doing a final vacuum purge to get remaining ethanol out of winterized Co2 oil? Barely see any bubbles and when U do its real slow like lava looking.
Lava like blurps, rather than fine bubbles, suggest retained alcohol.
Wow!
we extract with Co2, then winterize, then rotovap then, then purge for 24 hrs. I believe at 29.5 at around 115 F. Do you think that is adequate to get residual alcohol out? We test every batch, but just for THC, CBD, CBN haven't tested for solvents, but it daps and doesn't pop and gets you where you need to be quick!! All our oil tests out between 45-65% THC and our CBD runs are about 30-50% CBD.
when using the rotovap are you guys able to get all of the concentrate out or do you leave enough solvent for it to go into the next stage of purging?
Never tested my BHO, I've let the slooooooowly forming bubbles go on for a couple of hours, still no "small fizzy bubbles," and the big bubbles are at a fairly steady rate of bubbling after the forty-five minutes to an hour. I proffered my Lotus BHO, purged as described at Chalice, and was asked for repeat dabs, I couldn't tell the difference in behavior on the enails or in taste to any of the excellent oils offered to me in return. If a test of BHO purged to the simple standard I purge mine showed between 5,000 to 7,500ppm of butane I'd suggest the limit should be raised to 7,500ppm. Just saying my piece, so you know it, not willing to argue it at this time.
