Buchner 漏斗フィルターキット 1000mlフィルターボトルと250mlブフナー漏斗、G3ホウケイ酸ガラスラボ真空ろ過蒸留装置フィルターフラスコセット

Worked great for my needs! First package arrived broken but was replaced no problem two days later. Very happy. These do need special cleaning you just have to learn the process. Ignore other reviews saying “it can’t be cleaned “. Know how to maintain your equipment properly.

It's a little hard to clean without the right tools, but it works. I'm using it for a door stop.

The buchner funnel and erhlemeyer flask are well made and free of defects the #3 frit stops everything that doesn't dissolve. The hose that it came with collapses at -10 psi so it is virtually useless.

Clogs easily and doesn’t filter well at all pretty disappointed how can I replace the filter media?

Don't like the white stone in the funnel because it traps solids that you must work vigorously at cleaning out. Secondly I don't like the vacuum stem being used on the funnel, I rather it be on the flask because the design makes it difficult to clean the funnel specially with that irritating white stone in it as well also in a side note the little plastic locks could have been made of something a little more chemical friendly because mine got deteriorated and broke on the first time using it.
