I just did a 13lb biomass wash with 20gal of 200 proof. It took me 2 days to rotovap it back out. I’m rotovaping mu last 2 gallons of filtered recovered etoh from the panda now.
If you did a cryo etoh wash, no need to winterize, as cryo winterizes while you work. As long as its kept cold.
This is a 40 minute soak with 200 proof with food grade dry ice to keep cold! Then I use 3x 600ml buchner setups with fritted disc, and a bed of celite 545.
