coming back to this what temperature does a domestic fridge door actually swing to

unrelated but freezing reconstituted peptide is the one thing this channel has never agreed on, anyway

buy a thermometer

🤝1📈15👀1

powder is robust

quick one i left it out overnight by accident, bin it or use it
i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why

CH

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

GV

update from 14 months ago: replaced the fridge, temperature is stable, no more anxiety

CH

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

quick one for flying, hand luggage every time. the hold is not temperature controlled the way people assume

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

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

CH

lyophilised at room temp for 25 days in transit, worried or not

i log the fridge temperature daily and the room has never let me forget it

flying with vials, hand luggage or checked

KF

i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine, ask me again in a month

[edited]

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

CH

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

coming back to this anyone had a vial visibly change after a warm transit

[edited]

the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in

MN

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

my fridge is 5.6

CH

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

CH

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

back of the fridge

CH

cold pack arrived completely liquid, does that mean anything

log it

KF

power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well

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