i log the fridge temperature daily and the room

a reconstituted vial that has been at room temperature all day is a judgement call and mine is usually to bin it, roughly

never freeze reconstituted. the ice crystals are the problem, not the cold, research use only, not approved for human use

a few hours at room temperature is almost certainly nothing. a week is a different conversation, measured not guessed

whats the sensible plan for a power cut with a fridge full of vials

hope it settles, the last mile is the risk

i keep everything at the back of the middle shelf, never the door

a small cool bag with two frozen packs held under eight degrees for about nine hours in my kitchen test, 2 to 8 is the target not the law
