I’m interested as well.
Just out of curiosity more n anything.

Quality over quantity, using the equipment I have now, is the ultimate goal.

Using the mkiv and a 2lb column Hit 25% yields of dewaxed decent quality 80-90% thc extracts usually will be from properly ground up or machine nugs (taking out all the bad stuff before using the machine) or using kief

Around 25% using BHO or sub zero ethanol.

Hey GW it was BHO only a couple times got that high of a yield

Caribbean Smoke is on a distinguished road
We are currently running experiments in our lab to try to figure out how to optimize yield. We have noticed that soaking the material twice in butane/propane (Precision PX1) and not packing the columns too tightly gives us the best result.

However, we still see a lot of variability in yield when we convert BHO to distillate. We have a tried a few different short-path setups (monocow, three-port receivers, various boiling flasks). This is very frustrating. Our baseline assumptions are 50gm per pound of raw (not trimmed) flower, or 11% distillate yield.

Our process is BHO -> Degum (Citric Acid) -> Winterize -> RotoVap -> Short-path.

We are thinking of switching the Short-path to DCVC precisely because of the yield variability, but are just beginning to try this technique. For what it's worth, our observations are that the boiling flask of the SP should be run with the most amount of material possible. For example, we get better yields (as a %) when we fill a 5L boiling flask with 1,800gm BHO than with 300gm.

Can anyone with experience in DCVC tell me if the BHO -> Distillate yield is better or at least more consistent? Any critique on our process to help optimize yield?

Gray Wolf: I would like to have an email conversation with you about techniques if that is possible. Thank you.

Depending on strain, we typically see between about 18% to 22% using subzero techniques, but have seen 25% and heard of higher, just never personally seen one.

The next question of course becomes how much of it was target C-10/22 elements and how much non target such as C-20/34 plant fatty acids/waxes, C-40 beta Carotene, and C-55 Chlorophyll and Pheophytin.

My highest yield of all time was on some Reservoir Seeds 4SD, 23.5% (pure propane)
