Highlights from this day
- pbs_pip — for the archive lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear, take that with a pinch of salt 20:58
- cold_pack_carla — how cold is too cold, can it actually freeze in a normal fridge 21:13
- vat_on_import — unopened and in-use in the same place is fine. just keep the in-use one where you can reach it 21:23
- cagri_curious — for flying, hand luggage every time. the hold is not temperature controlled the way people assume 22:33
- cold_pack_carla — i have never had a lyophilised vial fail after a warm transit and i have had some bad ones 22:44

how do you keep it cold on a long drive in summer
i log the fridge temperature daily and the room has never let me forget it
if you are worried after a bad transit, test it. that is what the testing channels are for
for flying, hand luggage every time. the hold is not temperature controlled the way people assume
cold pack arrived completely liquid, does that mean anything
i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
