i keep everything at the back of the middle shelf, never the door
best travel setup for 22 days away with vials

a cooler with two gel packs held under eight degrees for eleven hours on a drive, happy to be corrected
i left it out overnight by accident, bin it or use it

thats fine

freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
genuine question i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
light exposure matters much less than temperature for these. i still keep them in the carton
log it
lyophilised at room temp for 11 days in transit, worried or not
if you are worried after a bad transit, test it. that is what the testing channels are for
does the amber vial thing matter or is it marketing
i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine

what temperature does a domestic fridge door actually swing to
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct, your mileage will differ
power cut for 3 hours, fridge stayed shut, am i fine
i would use it
does the fridge in a hotel room count as a fridge
my fridge is 3.1
how cold is too cold, can it actually freeze in a normal fridge
follow up do you log the fridge temperature or is that too far
gel packs
