log it

slightly off topic but a liquid cold pack tells you it was above freezing, not that your vial cooked

door shelf or back of the fridge

unrelated but nobody here can tell you a vial is safe. we can tell you what has and has not survived for us
unopened and in-use in the same place is fine. just keep the in-use one where you can reach it

hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct

power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well

i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine

if you are worried after a bad transit, test it. that is what the testing channels are for

my fridge is 4.8

i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why

freeze thaw cycling is the risk, not one freeze. that is my read of it anyway

best travel setup for 20 days away with vials

cold pack arrived completely liquid, does that mean anything
