Pyrex Flask, ERLENMEYER NARROW MOUTH ~ GLASS 2L

not a lot you can say about a giant flask, but it does what it's supposed to do, and seems as accurate as I need it to be. Nice flat bottom so a stir bar spins well. Using it for yeast starters, typically around 1.5l and it's been doing just fine.I have not boiled in it since I'm typically making a starter from grain, or previously pressure canned.

I use this for propagating yeast for brewing. It is sturdy and high quality. It is capable of receiving hot liquids. I use a magnetic stir bar on a stir plate and have had no issues with that either.The only difficulty would be that it is hard to clean, as any narrow-neck flask would be, so I recommend getting a large bottle brush with it.

Great product for making yeast starters. Glass is sturdy enough to not shatter when bumped. I'm not sure about how it handles heat, bc I did not heat the wort directly in the flask. 2L flask is a great size to make starters for typical beers; I would probably want a 3L flask to make high gravity beers.

I purchased this to make hot sauces and beer starter in. I wanted something large enough to make big batches. It works well with a stir bar, and it takes heat too.

Quality glass flask. I don't remember dropping this since I have owned it but it feels very well built. Not much else to say about it. It's a glass container with measurements on it and it feels sturdy.
