- noct.titrate — is there a difference in stability between the compounds the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in 13:08
a few hours at room temperature is almost certainly nothing. a week is a different conversation
the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in
unopened and in-use in the same place is fine. just keep the in-use one where you can reach it
for the archive freeze thaw cycling is the risk, not one freeze. that is my read of it anyway
two to eight degrees. most domestic fridge doors are not in that range and people do not check
update from 10 months ago: replaced the fridge, temperature is stable, no more anxiety
my fridge is running at 6.2, is that out of range
update on the earlier thing reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
do you keep the unopened vials and the in-use one in the same place

not the door
buy a thermometer
buy a thermometer. mine reads 7.4 on the door and two degrees lower at the back
does anyone freeze reconstituted vials or is that madness
log it
a cooler with two gel packs held under eight degrees for eleven hours on a drive
for flying, hand luggage every time. the hold is not temperature controlled the way people assume
lyophilised at room temp for 18 days in transit, worried or not
is there a difference in stability between the compounds
the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in
coming back to this is a five pound fridge thermometer actually worth it
