500ml Filtering Buchner Funnel Medium Frit (G2) Lab Glassware with Standard 24/40 Joint and Vacuum Serrated Tubulation, 94mm I.D, 100mm Depth

My son and I use this during the silver refining process and it's a godsend for speeding up the filtering process. What took 12 hours via gravity filtering is finished in 20 minutes with this vacuum filter!

Nice tight fitting s easy to use

I did not see this fact mentioned anywhere, but the vacuum tube adapter will fit a 3/8s inch line, such as a standard silicone rubber line used in brewing or plumbing. It arrived clean, unbroken, and was considerately packaged. No problems with delivery. I have yet to use it, but initial inspections are promising. Fits perfectly with the Erlenmeyer flask others bought with this item.

Works good and everything came in good condition. The medium frit has limited use and wish I would have opted for the fine frit but that was strictly my error and should bear no bad upon this filter.

Works like it should, haven’t broken it yet

Worked pretty well, cracked heating at 350 in my electric oven from cold to hot to cold without opening around the filter. This is my fault, the manufacturer didn't guarantee that it could withstand it, like the LABOY funnels do.

I broke two fritted Buchners from another brand in one week before finding this one. This one was actually made better and cheaper. The only way to clean these is with strong acids so be prepared for that that’s the price we pay for something that filters so fast and efficiently.

Nice filter. Noted you must use 94mm paper filters or it will clog and be uncleanable.

Arived in pieces. Replacement option
