Highlights from this day
- cat_on_the_tray — ok so flying with vials, hand luggage or checked 18:28
- vialkeeper — slightly off topic but power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well, i could be wrong 18:44
- meal_prep_mick — reconstituted solution is the fragile part. that is where the cold chain actually earns its keep if you are worried after a bad transit, test it. that is what the… 19:06
- meal_prep_mick — i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why 19:21
anyone tested a vial before and after a bad transit
does anyone freeze reconstituted vials or is that madness

do you log the fridge temperature or is that too far

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

a liquid cold pack tells you it was above freezing, not that your vial cooked
i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct
two to eight
i would bin it
a few hours at room temperature is almost certainly nothing. a week is a different conversation
if you are worried after a bad transit, test it. that is what the testing channels are for
parcel sat in a hot mailbox for 9 hours, is it dead
light exposure matters much less than temperature for these. i still keep them in the carton
