Highlights from this day
- impersonator_ip — if you are worried after a bad transit, test it. that is what the testing channels are for, happy to be corrected 21:12
- two_ml_two — the vial that visibly changed after a warm transit was the one that had already been reconstituted 21:15
- lyophile_liv — freezing reconstituted peptide is the one thing this channel has never agreed on i keep everything at the back of the middle shelf, never the door 21:17
- lyophile_liv — power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well 21:44
- impersonator_ip — is a five pound fridge thermometer actually worth it unopened and in-use in the same place is fine. just keep the in-use one where you can reach it 21:53
two to eight degrees. most domestic fridge doors are not in that range and people do not check

follow up does the amber vial thing matter or is it marketing
a liquid cold pack tells you it was above freezing, not that your vial cooked
flying with vials, hand luggage or checked
anyone tested a vial before and after a bad transit
a few hours at room temperature is almost certainly nothing. a week is a different conversation
door shelf or back of the fridge
power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well
coming back after 15 months, is the pinned storage table still current
coming back to this cold pack arrived completely liquid, does that mean anything
lyophilised at room temp for 15 days in transit, worried or not
update from 15 months ago: replaced the fridge, temperature is stable, no more anxiety
is a five pound fridge thermometer actually worth it
unopened and in-use in the same place is fine. just keep the in-use one where you can reach it
is there a difference in stability between the compounds
reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
does the fridge in a hotel room count as a fridge
i would bin it
