will the rubber resist acetone?

Cheap rubber won’t resist much

What is the temperature resistance of the rubber stopper? Thanks.

The stoppers are very cheap. I wouldn't reccomend, youre lucky if none show up broken

Lab-Quality

Used these for an experiment. They held up to high heat for over a week almost nonstop with no damage. Perfect! Plus they look cute and the stoppers work pretty well!

Good for costume/cosplay or decoration

Super cute. Great for costume or decoration. Glass is not thick like pyrex or anything. Rubber cork is a nice touch.

Great Flasks, Passable Stoppers

The glass is amazing, both thick and well made. Size is consistent, graduations are correct, and they could pass for genuine American borosilicate. Stoppers are iffy. I’ve had leaks from them, mostly when I open the flasks, and they seem to retain the liquid around the edges of the stopper. That said, they’re perfectly airtight. Great value for the set, and I appreciate the muted look of this brand. Nothing crazy, and they actually do mark the flasks, but it’s not overboard.
