After several uses and no material defects upon delivery - it is a win for the consumer
First things first, if you do decide to purchase this to use with a Buchner funnel you are absolutely going to need adapters or cones for your funnel. If you search "buchner funnel adapters" on here you should be able to find them.Glass arrived with no visible defects. Have used several times with a glorified aquarium pump and Buchner funnel for distillation and making tinctures. Works without issue, but the mouth of the flask is quite large and Buchner funnels tend to run "thin." To remedy this just buy adapters.

Should be sold with stoppers that fit!
The flask is great -- but the mouths of the ones that I received were barely 30 mm wide, so the stoppers that I ordered did not fit. The flasks should either come with stoppers that fit, or specify the ones to order.

Does what it is supposed to do! Great flask quality and economical buy!
Well it is what it is!...no complaints! I use it for making CBD oil works great with my Buchner funnel and vacuum pump! Even makes it easier to bottle by simply pouring out of the vacuum port straight into bottles!

Good, sturdy flask for boiling acidic solutions and robust enough for vacuuming with a Büchner funnel.

Rubber adapters
Works as it should, if this is a replacement and you don’t already know or own a adapter kit expect to have to purchase a kit of rubber adapters for any unmentioned filter funnels to fit properly. My hand cranked pump works just fine with it. Cleaning can be difficult. My personal opinion on it was money well spent as long as I don’t drop it again.

defective
This was a replacement for exact item. First had what looked like lots of little small chips on inside of bottom. This replacement has the same issue, almost like I got the same flask sent. To return they want me to wait 30 days for my money back, and 8 dollars to have it picked up. Bought a TON of stuff from stonylab, but this is really disappointing. Still better than QWORK stuff

Quality glass.
On second day I had it, I dropped from about 4-5 foot and all it did was bounce. It didn't crack or chip anywhere. Ive used several times since then under pressure and vacuum and it's just fine. Well made and very thick glass and came a day early.
