EISCO Erlenmeyer Flask, 1000ml - Borosilicate Glass - with PTFE Screw Cap - Conical Shape - White Graduations

Great quality glass with an inert cap, worked well for chemistry class.

Just as expected. Definitely recommend!

The glass is thin but works perfectly for my intended use.

Works for me. I did find a small chip on the bottom. I dont know if I caused it by setting it down hard. Id say you get what you pay for. Did the job just fine though.

The ptfe liner wasn't included, and I'll have to buy some ptfe sheets seperately.

I would have liked to have known the thickness of this beforehand. I don't feel it will stand up to the temps it claims, but more concerned about the cool down period cracking or popping it. Also doesn't have a drip ring. However, this seems to be (so far) a good entry level, or general use flask.

Bottom of flask scratched from PTFE stir bar after one use. Will need to discard. Otherwise it would seem like a good flask.

Didn’t last

Maybe I'm just used to expensive professional grade glassware and had my expectations a little higher than they should have been for the price point. The glass is slightly thinner /lighter duty than what I am used to at work, but for home use this is perfect. Works well, lid seals good.
