Highlights from this day
- swirl_not_shake — power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well, thats one data point 11:57
- swirl_not_shake — coming back to this a few hours at room temperature is almost certainly nothing. a week is a different conversation 12:03
- VialBot — Digest for the week of 2024-11-24 has been published. 12:06
- fridge_thermo — i log the fridge temperature daily and the room has never let me forget it 13:15
- bac_water_bill — for the archive lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear 13:30
i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why
my fridge is 4.8

unopened and in-use in the same place is fine. just keep the in-use one where you can reach it, we shall see
light exposure matters much less than temperature for these. i still keep them in the carton
reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
parcel sat in a hot mailbox for 3 hours, is it dead
a liquid cold pack tells you it was above freezing, not that your vial cooked
the door swings four or five degrees every time somebody opens it. the back barely moves
power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well, thats one data point
update from 16 months ago: replaced the fridge, temperature is stable, no more anxiety
swirl_not_shakepower cut with the door shut for a few hours is fine. a full fridge holds temperature…
power cut for 7 hours, fridge stayed shut, am i fine
the vial that visibly changed after a warm transit was the one that had already been reconstituted
coming back to this a few hours at room temperature is almost certainly nothing. a week is a different conversation
