Filtering Flask, Bolt Neck with Tubulation, 50-5000 ml

On second day I had it, I dropped from about 5 foot and all it did was bounce. It did not crack or chip anywhere. I have used several times since then under pressure and vacuum and is just fine. Well made and very thick glass and came a day early.

Works as it should, if this is a replacement and you do not 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 do not drop it again.

Nice size. Well packed. Arrived early.

Works excellent. Stony lab stuff is always top notch. I plan on sticking with them regardless of cost now. They are cheaper in the long run for most things.

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