hand luggage
slightly off topic but is there a difference in stability between the compounds
power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well
my fridge is 4
i log the fridge temperature daily and the room has never let me forget it
mon 4.1 / door 7.2
tue 4.0 / door 7.8
wed 4.2 / door 6.9
thu 3.9 / door 7.4
fri 4.1 / door 8.1 <- shopping day
sat 4.3 / door 7.0
sun 4.0 / door 6.8for flying, hand luggage every time. the hold is not temperature controlled the way people assume
i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why

i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine
lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
ok so i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
door shelf or back of the fridge
do i need to worry about light exposure or is that overthinking
how cold is too cold, can it actually freeze in a normal fridge
solution is not
a liquid cold pack tells you it was above freezing, not that your vial cooked
if you are worried after a bad transit, test it. that is what the testing channels are for
