I bought this flask for work with the synthesis of a very small amount of sulfur dichloride, and to do that i needed chlorine. So, in this beaker, i reacted hydrochloric acid & TCCA, and after using the chlorine, i let it vent some gas out of the top. I then sealed it and left it on my workbench because the yellow gas inside the beaker was kinda neat, plus i thought the reagents finished their reaction. Spoiler: They were not! Last night, about 4 days after i sealed it, the beaker exploded. Pieces went everywhere, thankfully nobody was hurt. I cleaned up the accident properly, and thought to myself how good of a seal that beaker must have had. Anything less than 5 stars would be a folly.

Every time I try to use a mag stirrer with this bottle, the stirrer gets off balanced after a few seconds and stops spinning. I haven't had this issue with other erlenmeyer flasks. It seems like the inside bottom is uneven. Outside of that, it's a great flask and includes a PTFE insert.

I like the thickness of the glass and the quality of the cap and its seal. At half the price it would be 5 stars and no complaints.

If the pour ring is important to you then know that this one does not have the pour ring like others do.

This flask is wonderful not only because of the great look but also the right seal.
