hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct

Highlights from this day
- dexa_or_bia — light exposure matters much less than temperature for these. i still keep them in the carton 19:02
- dexa_or_bia — unrelated but freezing reconstituted peptide is the one thing this channel has never agreed on 19:18
- a1c_lag — update on the earlier thing a liquid cold pack tells you it was above freezing, not that your vial cooked a few hours at room temperature is almost certainly nothing.… 20:01
- manila_meniscus — i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine 20:20
not the door
two to eight
parcel sat in a hot mailbox for 9 hours, is it dead
i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why
test it
unrelated but do you keep the unopened vials and the in-use one in the same place
how do you keep it cold on a long drive in summer
door shelf or back of the fridge

the door swings four or five degrees every time somebody opens it. the back barely moves
i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
what temperature does a domestic fridge door actually swing to

unopened and in-use in the same place is fine. just keep the in-use one where you can reach it, thats just me
does the fridge in a hotel room count as a fridge
ok so do you log the fridge temperature or is that too far
reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
follow up anyone tested a vial before and after a bad transit
power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well

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

my fridge is running at 4.8, is that out of range
follow up nobody here can tell you a vial is safe. we can tell you what has and has not survived for us
i would bin it
if you are worried after a bad transit, test it. that is what the testing channels are for

hand luggage
best travel setup for 10 days away with vials

cold pack arrived completely liquid, does that mean anything
right so lyophilised at room temp for 7 days in transit, worried or not

does anyone freeze reconstituted vials or is that madness
quick one coming back after 20 months, is the pinned storage table still current
