thats fine

i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why

best travel setup for 15 days away with vials

is there a difference in stability between the compounds

my fridge is running at 4, is that out of range

two to eight degrees. most domestic fridge doors are not in that range and people do not check

i left it out overnight by accident, bin it or use it

is a five pound fridge thermometer actually worth it

i have never had a lyophilised vial fail after a warm transit and i have had some bad ones

not the door

does the fridge in a hotel room count as a fridge

light exposure matters much less than temperature for these. i still keep them in the carton

two to eight

hand luggage

i would bin it

Purity check: no report on file for lot C-4402. Nothing logged either way.

unopened and in-use in the same place is fine. just keep the in-use one where you can reach it

not the freezer

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

powder is robust

buy a thermometer

does the amber vial thing matter or is it marketing

genuine question do i need to worry about light exposure or is that overthinking

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

buy a thermometer. mine reads 4 on the door and two degrees lower at the back, still working it out

how do you keep it cold on a long drive in summer

my fridge is 5.6

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

update from 9 months ago: replaced the fridge, temperature is stable, no more anxiety

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