2000ml Erlenmeyer Flask with Rubber Stopper (Single)

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.

We have purchased a few of these now for decanting wine. Look great, they hold up in the dishwasher and can take a decent amount of abuse.

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.

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 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.

Bought this to replace the Erlenmeyer that I previously broke. I was worried, because there are a lot of knock-offs on Amazon, but this is a real Corning Pyrex flask, which is much safer for using on a hot plate or cooling rapidly.

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.

Using this flask for yeast starter, good quality corning pyrex. Uses #10 stopper.
