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

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.

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

I find no flaws in this glassware. I see no bubbles or occlusions in the glass, the ground taper is concentric and even. There's absolutely not 1 thing that I can complain about

I am happy that the item was delivered earlier than scheduled. However, I think in the mist of things it had be thown around a bit leading to this crack above my thumb. I am hoping it is still usable and hope it will not crack further when adding heat. Overall, product is well made.

It works pretty well! The glass is solid for what I paid. I will however say I accidentally bought this thinking it was a fine frit. However it works pretty well if you add some filter paper!

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.

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!

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.
