the ice pack question that gets asked weekly, answered properly
the ice pack question that gets asked weekly, answered properly — a position I have arrived at slowly and would like tested.
Kept a vial at room temperature for eleven days by accident. Tested it out of guilt. It was fine.
Wrote the reconstitution date on the vial for the first time last year. Have never once since wondered how old a solution is.
Asked GGPeps which lines they hold regionally and got a straight list back. That answered my summer ordering question completely.
If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.
best — the order this archive was captured in
Gel packs are designed for a duty cycle. A liquid pack at the end of a longer-than-expected transit is a pack behaving as specified, not evidence of an excursion in the vial.
Put a logger in three consecutive orders. Two never went above the range at all and the third spent four hours warm on a Friday. Cost me almost nothing to stop wondering.
Moved everything off the fridge door after reading a thread here and my temperature log immediately got boring.
Same. Door shelf is the worst place in the fridge and it is where everybody puts them.
A stability statement is only meaningful with its conditions attached: temperature, duration, light exposure, and whether it covers powder or solution. Ask which.
Gel pack fully liquid on arrival, powder tested 98.4% against a claimed 97.5% afterwards. The pack had done its job for as long as it was designed to.
regional stock removes most of this problem entirely
Small fix — refrigerated, not frozen, once it is in solution.
