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

Everything is fine. It looks exactly like on the picture!

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.

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.

Working good under low vacuum (like Filter8) , but tearing the filter paper if vacuum become a little bit more strong.

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

die qualität ist nicht so toll 2 Löcher verstopft und die inneren Fläschen sind nicht behandelt. Dafür schnelle Lieferung.
