Highlights from this day
- brisbane_bac — do i need to worry about light exposure or is that overthinking i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand… 10:01
- underfill_uma — lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear 10:29
- underfill_uma — coming back to this do you keep the unopened vials and the in-use one in the same place 12:55
- underfill_uma — i left it out overnight by accident, bin it or use it 12:56
does the fridge in a hotel room count as a fridge
anyone tested a vial before and after a bad transit
do i need to worry about light exposure or is that overthinking
i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why
buy a thermometer. mine reads 5.6 on the door and two degrees lower at the back
parcel sat in a hot mailbox for 5 hours, is it dead
two to eight degrees. most domestic fridge doors are not in that range and people do not check
how do you keep it cold on a long drive in summer
update from 9 months ago: replaced the fridge, temperature is stable, no more anxiety
i would use it
lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
genuine question power cut for 4 hours, fridge stayed shut, am i fine
my fridge is 3.1
coming back to this do you keep the unopened vials and the in-use one in the same place

| Condition | Lyophilised | Reconstituted |
|---|---|---|
| 2-8 °C | fine, long term | fine, weeks |
| Room temp, days | fine in every report here | reported fine, shorter |
| Room temp, weeks | reported fine | do not |
| Warm transit, 30 °C+ | no failure logged | one visible degradant peak |
| Frozen once | fine | contested, no consensus |
| Freeze-thaw cycled | fine | the room says no |
a few hours at room temperature is almost certainly nothing. a week is a different conversation
