Room Temperature Winterization and Solvent Removal

I have certainly run into some issues with them.

I need to nail down exactly which membranes we have on site, and quantify how they’re performing, but as of right now I’m not convinced.

  1. a significant amount of THCA is being retained with the waxes, I can’t actually quantify that this week, as I just dropped my GC off in Vegas for repair (primary reason I was at MjBizcon). So our goal of EtOH shatter will need rethinking.

  2. seems the membranes are “set it & forget it”…by which I mean they become “set” to whichever solvent they are initially conditioned with. I my case that means the initial R&D done with methanol has hamstrung me. flow rates with ethanol are a mere fraction of what they were with methanol… and that looks to be a non-recoverable error. so once again: Ethanol shatter? forget it! &$^(&)#@

not my lab. not my membranes. not me who used methanol for the exploratory work.

still my problem…

Has anyone else run into these issues and solved them?
