[Question] how do you actually verify data logger
Trying to get a straight answer on this: how do you actually verify data logger. On loggers, since I was sceptical and then bought one. A small transit logger costs a fraction of a vial and records the whole journey rather than the moment of arrival. What I learned from three of them: my lane is far more stable than…
I would not freeze it in solution. That is a different failure mode and a worse one.
regional stock removes most of this problem entirely
Agreed on seasonality. The same lane in February and August is not the same lane.

This.
Disagreeing with this line only: freezing a reconstituted vial is not a safe default.

This is the distinction that resolves most threads here — powder and solution are different problems.
This.
Agreed, and a logger costs less than the vial you are worrying about.
