Great for starters!
I use this for yeast starters for brewing. High quality and priced lower than my LHBS. My only complaint is that the supplied stopper is made of a VERY strong smelling rubber. I used it to keep dust out during storage, but promptly discarded it and replaced it with a solid stopper from my LHBS due to the odor.

These will get the job done if you are on a budget. The only downside (and reason for my 3 star review) is that the labels/numbers will fade if you wash the outside with harsh chemicals. Alconox detergent will fade the labels after repeated use. I guess if you are carefull on the washing, it wont be a problem. Just dont get any harsh chemicals on the outside labels.If you want something a little more lasting pay twice the amount and get some Pyrex. The Pyrex labels will not fade.

Fine price, solid feeling product, one caveat.
Can't beat the price but be aware this flask has a slightly curved bottom; this -I'm told -helps the durability and thermal properties of the glass but makes using a stir bar difficult, especially for homebrewers looking to culture or start yeast in one.For 10 bucks I'm not super upset about it not working out perfectly, and I'm sure I'll find other uses for it, but I will be scouting out a confirmed flat bottomed flask to replace it for yeast starters.

Stopper too big
Seems like a sturdy flask, has already whipped up one yeast starter for me. HOWEVER, the black rubber stopper provided is too large for the flask, no way on earth it is fitting in.

No rubber stopper included!
Bad product. I bought it especially because of the rubber stopper which was not included!!! This only shows that the web description is not accurate or they are stealing from me.

A good flask for yeast starters.
I always get the simple reviews. Yup, it's a flask. Yup it's 1 liter. I use this flask for making yeast starters, and yeast harvesting for homebrewing. This is the perfect size for my application and it works flawlessly with my stir plate.My only complaint was the shipper packed it sloppily. The padded envelope they used inside the package got stuck to the flask. The glue from shipping envelopes is some tough stuff. Nothing an overnight soak in Oxy couldn't fix though.
