back of the fridge

anyone had a vial visibly change after a warm transit

my fridge is 4.8

reconstituted solution is the fragile part. that is where the cold chain actually earns its keep

gel packs

freeze debate again

buy a thermometer. mine reads 3.1 on the door and two degrees lower at the back

coming back after 5 months, is the pinned storage table still current

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

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

lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear

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

two to eight

how long is reconstituted actually good for at room temperature

if you are worried after a bad transit, test it. that is what the testing channels are for
