OP has a small CLS, and is not clear that they want to purchase a ROTOVAP…where on earth are they going to come up with the tooling to “try a CO2 extraction”?!?
even if we imagine they have the required $100+ k machine lying around, how does extracting with CO2 get them any closer to water clear distillate?
it’s not like they could then skip any of the above steps…
Edit: technically CO2 can be done for a couple or $3k. See Open blast CO2 just not at a scale that leads to distillate
