stonylabPorcelain Buchner Funnel 80mm, Porcelain Buchner Filter Funnel OD 8cm ID 7.4cm for Laboratory

Sturdy, as all is well so far.Adapting it for a coffee brewing basket ( for a pour over )

If you're like me and messed up in Chem lab, this is a great fix. It's not the quality you will find from the insane multi-hundred dollar funnels that the college uses but this one gets the projects done without complaints.Serves its purpose, ceramic, and has an excellent price.

Excellent product manufactured perfectly! Easy to use and clean!

Works well it's your standard filtration funnel at a little filter paper and it works wonders. It's a little rough around the edges but what do you want for the price for your amateur chemist it works fine

good

This filter works great with the size 74mm the company sells. The problem is that if you need more filtration like I do you have to go from the 10 microns to a syringe filter of .45 um. Extremely hard on the hands and every 20-25 ml or so you need a new filter. Would be useful if they had a 1-micron filter or close to that. If you need to filter less than 10 microns this is not for you. I have tried to find filters in other provider, but the size doesn't match.

all ok

I’ve never used a Büchner funnel so I initially assumed I was doing something wrong. Eventually I dropped a flat object onto the bottom of the funnel. The surface is higher in the center (by a lot), so the filter paper won’t conform unless it’s very thin, very wet and you get lucky. Also, I had to trim their 56 mm diameter filter paper to get it to work at all. I’ll be purchasing lab equipment from a US based manufacturer from now on.

Perfect size for what I need. Was packaged well and arrived with no damage.

Filteration

Ich verwende den Trichter dafür, Tinkturen zu filtern. Durch die Größe des Trichters geht das schneller und bequemer. Wenn ich mit Filterpapier arbeite geht auch die Reinigung leicht und schnell. Gutes Preis/Leistung Verhältnis.
