Does quality stay the same across vials in one kit?

I'm wondering whether anyone has noticed differences in quality from vial to vial inside the same kit. Say a kit (whether tested or untested) is giving you good results, and then a single vial from it appears to be bunk. That doesn't sound like something that happens often, or really at all, but I'm curious.

A similar question came up not long ago and got no replies, and I thought it was worth asking. Fingers crossed it's a non-issue!

So far I'm having excellent results with everything I've received 🙂

Look at how much active compound each vial or kit contains, and then consider the way they manufacture within a cycle. My view is that significant variation between vials from the same kit would be unlikely.

I brought this up in a different thread on here. The concern there was about variation between vials in the same kit.
 
In the testing I've come across, the differences between individual vials have been extremely minor. When vials out of a single batch are grouped together in tests, their results land very near one another, and I don't remember a variance test where a single vial came up short on purity or on Endotoxins. Assuming everything truly comes from one batch, the variation in purity or endotoxin levels is minuscule — and much of that is likely down to the limits of the test's resolution rather than actual differences in how it was produced.

That explanation seems the most plausible to me.

That said, problems can arise from kit to kit when different batches get mixed together.

Still, I'd argue that finding differing vials inside one kit is far less likely — though not impossible.
