QWORK Borosilicate Glass 500ml Buchner Filtering Funnel and 1000 mL Erlenmeyer Flask, with Standard 24/40 Joint

So, I make wine for a living. I had broken my 250mL buchner funnel and needed to get a replacement as fast as possible. This 500mL was the only thing on Amazon available. First, it is big. It is very nice to be able to filter a 375mL sample bottle all at once. The papers i ordered for it fit perfectly and it did a beautiful job of clarifying the wine samples. Larger surface area of the paper also made for not having to stop half way through and change out the media. Nice, heavy glass. Great quality. Easy to clean and keep clean. For the price, go for it. Hard to beat.

Works great

Appearance is just as described and shown in the pictures. Fit is perfect, the funnel fits the flask flawlessly. Durability is good enough and as expected from Borosilicate Glass Versatility is good, you could use this for any number of things, even filtering coffee. Value for Money, yeah I would say this is a pretty good value.

First - the glass is not 100% lab grade. It may have some inclusions and some internal chips. Second - the funnel under vacuum is amazing. But I think that's true of any simular funnel. Got this for the size of the cup. The built in separator is kind of silly and hard to clean. Not really suitable for chemicals or powder filtration unless you put more filters in it and prevent the fines from passing throguh. I suppose this is similar for any such funnel and a known lab issue.

Best deal by far on this item. I was about to pay $138 for a similar item that came with the vacuum. I bought this and the vacuum for like $70.

Hands down best deal ever. The best deal you'd get on the funnel alone is $29.99, and same for the 1L jointed Erlenmeyer flasks. I read one person received low quality glass, but I've purchased 2x and was pleasantly surprised by the high quality. (I broke the first flask but still use the funnel). I'll be purchasing more as soon as I inevitably drop something while cleaning... what I mean is I wouldn't trust this glass to blowtorch directly to warm up when things crash out, but besides the frit being about ⅔ the normal thickness, they didn't skimp on the structural glass. I think the frit is ideal for most vacuum filtration, as filling it without vacuum is enough for continuous flow until the particles begin to pack down.

works well, and sized well for the money. The porous disk is much more efficient than a bunch of little drain holes.

Works great. Joints fit perfectly. I haven't heated it to test the quality of the glass, but that's not really the intent for this setup.
