Highlights from this day
- reta_resting_hr — is there a difference in stability between the compounds freeze thaw cycling is the risk, not one freeze. that is my read of it anyway 21:20
- auckland_aliquot — i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine 21:43
- dez_domains — 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.… 21:47
cold pack arrived completely liquid, does that mean anything
how do you keep it cold on a long drive in summer
[edited]if you are worried after a bad transit, test it. that is what the testing channels are for
log it
i would bin it

ok so light exposure matters much less than temperature for these. i still keep them in the carton
my fridge is 5.6
for the archive how cold is too cold, can it actually freeze in a normal fridge
is there a difference in stability between the compounds
freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
a cooler with two gel packs held under eight degrees for eleven hours on a drive
i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
freeze debate again
buy a thermometer

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