The one I got had a cap. Not sure what went wrong.... Maybe I'll try a better setup. Vac pump will run you around 100-150 for a single stage 200-250 for 2 stage. (Lower end entry level type)Didn't work, too bad. Did you poke a small hole in top of the foil?
How much is the vacuum pump?
Honestly, I think the one I got is junk. I'm gona try again with a diff Buchner funnel. I need to research the frit and see whether G1, G2, or G3 would work better.I use a Büchner funnel and a vacuum pump for bench-scale work. The liquid will be trapped in the Buchner and the filter will hold the solids back. It should dewater, don’t see why this wouldn’t work. The part in the video about the oil somehow mixing with the product is none sense- literally impossible
The vid u posted shows a small hole in the rubber banded foil lid, for some suction air release.It has a really stupid clamp that connects the funnel to the beaker, where I believe I'm loosing vac
Ya I might try it with the foil lid and poke a hole. Maybe that has something to do with it. I'm exploring some new ideas so there's bound to be a learning curve.The vid u posted shows a small hole in the rubber banded foil lid, for some suction air release.
It's a 300ml funnelYou don't need a pump. A faucet aspirator pulls hard enough. I dont think it's your pump.
@Jjgrow420 are you using a big ass buchner like in the vid? If so, I'm going to go ahead and guess if you are, you're pulling too much air around the hash and not the hash direct enough, if that makes sense.
I just used the 25u pressing screen. Water passes through that easily so I figured it's the same deal?Did you use quantitative filter paper?
It does make sense. I tried placing the hash right on top of the frit (on the screen of coarse) and even packing the screen around the sides of the funnel so the air would pass right through the hash. I'm thinking @doughper might be on the right track with the small hole on top forcing the air through the funnel more. Will try it before I send it back to amazon.You don't need a pump.

Lol I tried. Got frustrated and threw in the towel last night. We go for round 2 tonight.tape that biotch up and pull some vacuum, man!
I think this may be the issue. Mine has a gasket that seats the filter in the glass. Shouldn’t take much vacuum it would seem (but I have never tried it lol)It has a really stupid clamp that connects the funnel to the beaker, where I believe I'm loosing vac. So I can never get down to -29.9hg. Prob why it's not pulling the water out.
My experience with buchners was for filtering purposes, cleaning up chlorophyll from extractions. So I never tried with a solid ( hash) But I would make two filters out of diatomaceous earth and carbon that started as slurrys, and when I pulled a vacuum on them, they really dried out and became solid. So i really dont see why this wouldn't work.It does make sense.

I was looking for a 24/40 fitting funnel male and 24/40 female extra thick beaker but shipping would have taken a couple weeks and it would have been double the price.I think this may be the issue.

The paper is a really low mircon, so it would probably help with the vacuum. I've never seen a buchner funnel being used with any other type of filter.I just used the 25u pressing screen. Water passes through that easily so I figured it's the same deal?
Ah, I see what your saying. Well I'll try this hole deal first see what happens, next step would.be proper paper. But I think in the vid he said he was using a press screen. I can't fully remember lol that was yesterdayThe paper is a really low mircon, so it would probably help with the vacuum. I've never seen a buchner funnel being used with any other type of filter.
