What is the best column filter design after Ethanol?

At that scale and with your goal, I suggest this thread:

If you need anything regarding how one can modify this process to speed it up, let me know, and remember that if you are trying to get that beautiful golden extract (without distilling), the filtration is going to be slow and the extraction should be done as cold as possible.

I have also found that with this process in particular, pushing works way better than pulling. Nitrogen for the win, all day long!

Edit: I also second what @ky_cbd said about graduating your filtration. It is necessary to maximize speed and prevent fouling/blinding of your filters. Super important not to jump straight from extraction to one’s smallest desired pores size.
