not sure what grade this is
my flasks came with scratches, bubbles and chips not sure I would put these on a flame and waste the yeast if it exploded. I will be sending these back. They don't even say that they're pyrex. No wonder they recommend the double boiler method these flasks are wonky at best

Works with my stir plate
No issues with my stir plate. Stir bar holds tight in center of this flask at all speeds even though the bottom is slightly concave. A high quality stir plate with strong magnets may over come the drawback of a concave bottom. The graduation markings are "approximate." This isn't an issue for me because I use measuring vessels that are more accurate as a work around. This flask is priced appropriately for what you get, which is why I purchased it. My equipment was able to overcome the slight flaws easily, which made this flask usable for me and a bargain.

Inaccurate volume markings
The two 5L flasks I received were not Bomex flasks and the volume markings are way off. We’re paying $40 for these and they’re not even graduated correctly!

Awesome Product
This thing makes large yeast starters so much easier than my old 2L flask. No more worrying about waking up to a mess. It's also great to boil directly on the stove and chill directly in the sink, less chance for contamination.

My current stir plate is struggling to keep up, although that's because it was made for 2L flasks.

I really like the size of this flask. It makes a very good starter for my wine making. Are use a stir plate when using this and everything went very well.
