i keep everything at the back of the middle shelf, never the door

Highlights from this day
for the archive hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct
quick one does the amber vial thing matter or is it marketing
freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
unopened and in-use in the same place is fine. just keep the in-use one where you can reach it, for what its worth
a cooler with two gel packs held under eight degrees for eleven hours on a drive
does the fridge in a hotel room count as a fridge
a few hours at room temperature is almost certainly nothing. a week is a different conversation
do you keep the unopened vials and the in-use one in the same place
hand luggage
log it
nobody here can tell you a vial is safe. we can tell you what has and has not survived for us, ymmv
freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
coming back after 8 months, is the pinned storage table still current
the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in
quick one how cold is too cold, can it actually freeze in a normal fridge
😂17🎉3
right so do i need to worry about light exposure or is that overthinking
two to eight degrees. most domestic fridge doors are not in that range and people do not check, not advice obviously
i would use it
freezing reconstituted peptide is the one thing this channel has never agreed on
buy a thermometer. mine reads 4.8 on the door and two degrees lower at the back

light exposure matters much less than temperature for these. i still keep them in the carton
lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
i left it out overnight by accident, bin it or use it
power cut for 3 hours, fridge stayed shut, am i fine
🎉3👍1
if you are worried after a bad transit, test it. that is what the testing channels are for
i log the fridge temperature daily and the room has never let me forget it
gel packs
coming back to this i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why, from memory

not the door

how do you keep it cold on a long drive in summer
my fridge is 5.6
cold pack arrived completely liquid, does that mean anything
reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
how long is reconstituted actually good for at room temperature

for flying, hand luggage every time. the hold is not temperature controlled the way people assume
👍1
flying with vials, hand luggage or checked

the vial that visibly changed after a warm transit was the one that had already been reconstituted

the door swings four or five degrees every time somebody opens it. the back barely moves
i would bin it
