Highlights from this day
- gall_bladder_gav — unopened and in-use in the same place is fine. just keep the in-use one where you can reach it, i think 21:51
- knees_first — i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine 21:52
- knees_first — flying with vials, hand luggage or checked 22:38
- LC_MS_Lena — hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct 22:41
i would bin it

the door swings four or five degrees every time somebody opens it. the back barely moves
update on the earlier thing i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why
nobody here can tell you a vial is safe. we can tell you what has and has not survived for us
update from 3 months ago: replaced the fridge, temperature is stable, no more anxiety
[edited]gel packs

light exposure matters much less than temperature for these. i still keep them in the carton
test it
lyophilised at room temp for 5 days in transit, worried or not

buy a thermometer. mine reads 4 on the door and two degrees lower at the back
is a five pound fridge thermometer actually worth it
[edited]coming back after 9 months, is the pinned storage table still current
i would use it

thats fine
for the archive i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear

buy a thermometer
how long is reconstituted actually good for at room temperature
best travel setup for 15 days away with vials
log it
not the freezer
a liquid cold pack tells you it was above freezing, not that your vial cooked
does the fridge in a hotel room count as a fridge
two to eight
anyone had a vial visibly change after a warm transit
hand luggage
freeze debate again
flying with vials, hand luggage or checked

if you are worried after a bad transit, test it. that is what the testing channels are for
the vial that visibly changed after a warm transit was the one that had already been reconstituted
cold pack arrived completely liquid, does that mean anything
solution is not
ok so a cooler with two gel packs held under eight degrees for eleven hours on a drive
