Highlights from this day
  • dexa_or_bia — sorry to jump in i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why i freeze aliquots and have had them test… 23:05
  • VialBot — Purity check: no report on file for lot A-2418. Nothing logged either way. 23:17
  • auckland_aliquot — for the archive nobody here can tell you a vial is safe. we can tell you what has and has not survived for us 23:35
  • auckland_aliquot — if you are worried after a bad transit, test it. that is what the testing channels are for 23:40
  • auckland_aliquot — unopened and in-use in the same place is fine. just keep the in-use one where you can reach it, still working it out 23:46

buy a thermometer. mine reads 4 on the door and two degrees lower at the back

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

best travel setup for 20 days away with vials

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

*sorry, JEEP

two to eight degrees. most domestic fridge doors are not in that range and people do not check

hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct

cold pack arrived completely liquid, does that mean anything

a few hours at room temperature is almost certainly nothing. a week is a different conversation

light exposure matters much less than temperature for these. i still keep them in the carton

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

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

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

i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine

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

update from 15 months ago: replaced the fridge, temperature is stable, no more anxiety, we shall see

freezing reconstituted peptide is the one thing this channel has never agreed on
