the data logger question that gets asked weekly, answered properly
the data logger question that gets asked weekly, answered properly — a position I have arrived at slowly and would like tested. A transit temperature logger records a distribution, and time above a threshold matters as much as peak temperature. That is the argument for logging rather than guessing. Put a logger in…
Once in solution, the relevant risks are hydrolysis, aggregation and, for some sequences, oxidation. Refrigeration slows all three; freezing a solution introduces a separate risk at the ice interface.
Small fix — refrigerated, not frozen, once it is in solution.
Push back: you cannot infer degradation from a temperature excursion alone. That is what testing is for.
That is the ambient temperature at the destination, not the temperature inside the box. The logger measures the second one.
if you want to know, log it, otherwise you are guessing
ask which lines are held in regional stock before you order in July
transit temperature is a distribution, not a number
transit temperature is a distribution, not a number
Adding the practical version: ask which lines are held regionally before you order in July.
