a few hours at room temperature is almost certainly nothing. a week is a different conversation

Highlights from this day
- swirl_not_shake — the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in 08:48
- swirl_not_shake — unrelated but buy a thermometer. mine reads 3.1 on the door and two degrees lower at the back, n of 1 obviously 09:05
- swirl_not_shake — does anyone freeze reconstituted vials or is that madness 11:18
nobody here can tell you a vial is safe. we can tell you what has and has not survived for us
for flying, hand luggage every time. the hold is not temperature controlled the way people assume
the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in
a liquid cold pack tells you it was above freezing, not that your vial cooked
power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well
unrelated but buy a thermometer. mine reads 3.1 on the door and two degrees lower at the back, n of 1 obviously
freeze debate again
freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
update from 22 months ago: replaced the fridge, temperature is stable, no more anxiety
the door swings four or five degrees every time somebody opens it. the back barely moves
does anyone freeze reconstituted vials or is that madness
