That logic falls apart pretty quickly if you follow it all the way through. If you can’t trust a sterile vial or filter because you personally didn’t verify the sterility, then you also can’t trust syringes, needles, media bottles, pipette tips, or basically any sealed lab consumable.
Sterile consumables exist specifically so labs don’t have to individually test every item. They’re manufactured in controlled environments and sterilized in batches, then sealed. The entire research industry runs on that model.
The real variable is the supplier. If you’re buying lab-grade consumables from reputable vendors, the risk is extremely low. If you’re buying random no-name stuff from questionable sellers, that’s a different conversation.
But the idea that every sterile vial or filter is suspect unless you personally test it would mean you can’t trust any manufactured lab consumable at all, which obviously isn’t how research works.
