Big flask for going big time
This flask is so big it looks cartoony. It works well and didn't explode when I put it directly on an open flame on my stove, and again when I put it directly in an ice bath for cooling. Recommended!

Rehydrate dry yeast or grow up starters
I use these as a second or third step when growing up yeast from plates or slants and also to rehydrate dry yeast. To do so, I fill it halfway with wort or water (for growing or rehydrating yeast respectively), add a stir bar, cover it with foil and then cook it in my pressure cooker. That way I have sterile wort or water when I need it for yeast handling.

I also sometimes use these on the stove and haven't had a problem yet. The glass is pretty thick and durable, although I don't recommend putting it directly in cold water from the stove.

It came well packaged in bubble wrap, so it should arrive safely.

sturdy container! does it all.
just don't put it on the stove, don't think it is rated for that. i use it for stepping up starters and it is great.

Nice size
This is a nice item when your doing starters. I use it to step up my starters. It's sturdy. I also like to use it during slanting to hold sanitizer which I put my inoculating loop in. Multitude of uses.
