Metal seems crimped properly. Definitely not test lol. That's a simple "toss and replace" as you say.Is the metal crimped on securely? My only thought is when crimping the top the rubber got pushed in before the metal grabbed the glass lip and then when it did it kept the vacuum then with no way out.
I’d say it’s fine but if it’s just test I may toss. Maybe “risk” and use if it’s an exotic. But I Homebrew test and each finished vial is about $5 total probably in ingredients.
This is the only one like that and the only time I've ever seen this occur.Hmmm...interesting. Your other vials from same sponsor the same?
Cool, I wasn't aware of these. Thank you man.You can use a sleeve stopper to replace that collapsed stopper.

Yes! When the liquid was put in there hot it made the air in there warm too and less dense, pushing some air out of the vial. Then you put the stopper on. After it is sealed it starts to cool and the air becomes more dense and contracts, drawing in the stopper.More than likely put in the vial while still hot. Crimped. This is the result. Would be my best guess.

You might have had this same experience putting hot meat into tupperware and sealing it with the lid.
