Does anyone know out of experience if a vacuum filtration setup (large buchner funnel, vacuum flask and water aspirator or handpump) does work properly when trying to recover solvents from a cactus STB mush?
The only applications I could found so far in instruction vids and docs on the net are recovering crystals from solvents. I wonder if the vacuum will be powerfull enough to suck solvent densities like cactus mush.
I'm looking at a 28 cm diamer buchner and a 2000ml vacuumflask. Will this work or should I keep the coffeepress/coffeefilter for this process?

yes.

Great! Thanks.
