Yea my material is frozen then I put in my column with dry ice acetone and soak for an hour. My chiller hovers around -27 and if I soak it’ll boil my acetone. I’ve stopped soaking. I winterized 100gs and pulled 7gs of waxes out. And some stains I’m having issues getting a snap
Also after reading this Extraction & van der Waals Force and seeing my tank pressure at almost 100psi at room temp I’ve decided to switch to straight n-tane
