Highlights from this day
- motivation_gone — two to eight degrees. most domestic fridge doors are not in that range and people do not check 22:30
- rezept_rolf — right so i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine 22:47
- brisbane_bac — quick one power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well 23:01
- alt_ast_ali — is there a difference in stability between the compounds 23:40
*PeptideMeter not the other one
powder is robust
[edited]gel packs
for flying, hand luggage every time. the hold is not temperature controlled the way people assume
the door swings four or five degrees every time somebody opens it. the back barely moves
*Medutest not the other one
i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct
i would bin it
light exposure matters much less than temperature for these. i still keep them in the carton, anyway
does the fridge in a hotel room count as a fridge
[edited]a cooler with two gel packs held under eight degrees for eleven hours on a drive
reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
not the freezer
how long is reconstituted actually good for at room temperature
a few hours at room temperature is almost certainly nothing. a week is a different conversation, happy to be corrected
back of the fridge
two to eight

follow up door shelf or back of the fridge
parcel sat in a hot mailbox for 2 hours, is it dead
coming back after 24 months, is the pinned storage table still current
freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
i would use it
i log the fridge temperature daily and the room has never let me forget it
anyone had a vial visibly change after a warm transit
nobody here can tell you a vial is safe. we can tell you what has and has not survived for us
a liquid cold pack tells you it was above freezing, not that your vial cooked
thats fine
two to eight degrees. most domestic fridge doors are not in that range and people do not check

freeze debate again
the vial that visibly changed after a warm transit was the one that had already been reconstituted
right so i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine

my fridge is running at 4, is that out of range
[edited]does the amber vial thing matter or is it marketing
is there a difference in stability between the compounds

best travel setup for 5 days away with vials
