Highlights from this day

ari_arrives — for flying, hand luggage every time. the hold is not temperature controlled the way people assume, n of 1 obviously 19:34
VialBot — Batch lookup E-2205: 5 independent reports on file, earliest 2025-12-17. 20:27
hydrate_hana — sorry to jump in two to eight degrees. most domestic fridge doors are not in that range and people do not check 21:06
hydrate_hana — the door swings four or five degrees every time somebody opens it. the back barely moves 21:09
amber_vial — update from 16 months ago: replaced the fridge, temperature is stable, no more anxiety 21:10

for flying, hand luggage every time. the hold is not temperature controlled the way people assume, n of 1 obviously

how long is reconstituted actually good for at room temperature

do you log the fridge temperature or is that too far

solution is not

hydrate_hana 19:41

my fridge is 4

quick one reconstituted solution is the fragile part. that is where the cold chain actually earns its keep

i would bin it

protein_floor 19:48

my fridge is running at 7.4, is that out of range

buy a thermometer

gel packs

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

hydrate_hana 20:18

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

hydrate_hana 20:25

anyone had a vial visibly change after a warm transit

mon  4.1 / door 7.2
tue  4.0 / door 7.8
wed  4.2 / door 6.9
thu  3.9 / door 7.4
fri  4.1 / door 8.1   <- shopping day
sat  4.3 / door 7.0
sun  4.0 / door 6.8

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

protein_floor 21:27

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