upgraded to 2000ml buchner for filtering ethanol extract. after winterizing, i would like to add ac, ao and celite, making a patty style with another paper on top. question is- what grade paper? was looking at grade 5 and 6 to prevent powder from sucking through. recommendations for paper and how you do filtrate stacks? turns out 185mm paper too big, need 180- some trimming ahead! thanks
Why not use a fritted disc buchner funnel? It will stop all the fines from sneaking through.
A proper celite layer at the bottom of your cake will stop the fines from coming through. I like to use a fritted buchner with a paper over the frit for good measure. Here’s a nice explanation of building a filter cake in your funnel:

what grade of filter?2, 3, 5 or 6? when and how do you use the ao?
thanks
im using a ceramic 2l buchner. if i get another i was thinking about the 4l plastic buchner at torr kitchens. i avoided the fritted disc because i heard they clogged easily and were very hard to clean. im just a home cook, but i am extracting 12lbs at a time using 10 gals pure ethanol- so i have alot to process per batch. making feco and trying to end up with 500ml+ of concentrate
thanks!
