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

do you keep the unopened vials and the in-use one in the same place

powder is robust

parcel sat in a hot mailbox for 5 hours, is it dead

Reminder set. I will post here in 7 days.

follow up nobody here can tell you a vial is safe. we can tell you what has and has not survived for us

Channel stats, last 30 days: 55 messages from 13 members.

update on the earlier thing my fridge is running at 5.6, is that out of range

cold pack arrived completely liquid, does that mean anything

door shelf or back of the fridge

two to eight

i would use it

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

Reminder for amsterdam_aliquot: dose day is today. Set 4 days ago.

slightly off topic but anyone tested a vial before and after a bad transit

how long is reconstituted actually good for at room temperature

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

unrelated but light exposure matters much less than temperature for these. i still keep them in the carton
i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine

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