Does anyone have experience with some of the commercially available vacuum filters or ideas for diy?
I’m in need of a better filtration setup for cold ethanol extraction. I’m currently using a 2L fritted glass buchner funnel with 5L flask. Using a celite bed it works pretty good, but it is a pain to keep having to empty the flask and could use something larger to save time. I am filtering 5-10gal at a time.
I’ve seen the large table top buchner from bel-art, but read that they have problems with leaking. I know usa labs has a stainless steel 6in and 12in filter that looks promising, but have not heard if they work well. They just posted a new setup in IG with a modified keg as collection base. https://www.instagram.com/p/Bs_J9-fhoUH/
BVV has a stainless refinement filters as well and 20l collection base which would be really nice to be able to hook up to feed the rotovap. https://www.bestvaluevacs.com/bvv-refinement-filter.html
Summit has the hochstrom filter, that seems like a good design. Also a really nice collection bottle with vaccum ports, but seems really expensive for what it is. https://summit-research.tech/product/hochstrom-filter/
