Try doing a really short run, less than 30 minutes, at around 1100-1200psi, and 70-80F. I believe this will pull a nice terpene fraction that you can harvest, then after harvesting the terpenes, put your collection cup back onto the machine, and finish out a complete run at higher pressures and temps just to speed things up. Then, winterize your oil, and after winterizing, you can re-introduce your terpenes back into your oil. The terpene fraction may have some water, and lipids etc. in it, you will need a separatory funnel and maybe a small syringe to remove the water and lipids. I hope this helps a little!So i've been working with a Apeks 5000 20L. If i do my first run as low psi as possible on the extractor i get an oily substance coming out that looks like sludge. a light brown to a dark brown color. anything higher i start getting a mix of this and the crumbly waxy stuff. yesterday i had the first run sent to the lab for a terpene analysis as it's much more fragrant than the higher pressure stuff. how do i refine this first pull stuff? i'm going to try winterizing it and then using the rotovap once i get my cold trap setup as i've noticed i'm losing terpenes when i reclaim my ethanol.
