Buchner Funnel Filtering Kit with 1000 ml Filter Bottle and 250 ml Buchner Funnel, G3 Borosilicate Glass Lab Vacuum Filtration Distillation Apparatus Filter Flask Set

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.

hi quality, and exactly as the said it would be

The built-in filter clogged and is impossible to clean after the first use, rendering the device useless. Do not waste your money on this.

the non removable filter is next to impossible to clean. i thought not needing filters would be great but i was way wrong
