Highlights from this day
- cedar_counts — slightly off topic but coming back after 21 months, is the pinned storage table still current 01:24
- split_dose_sam — freezing reconstituted peptide is the one thing this channel has never agreed on 01:27
- meal_prep_mick — how cold is too cold, can it actually freeze in a normal fridge 02:36
- cold_chain_cmdr — coming back to this a cooler with two gel packs held under eight degrees for eleven hours on a drive 02:48
the door swings four or five degrees every time somebody opens it. the back barely moves

how do you keep it cold on a long drive in summer
freezing reconstituted peptide is the one thing this channel has never agreed on

*Janoshik not the other one
i would bin it

the vial that visibly changed after a warm transit was the one that had already been reconstituted
how long is reconstituted actually good for at room temperature
is a five pound fridge thermometer actually worth it
i log the fridge temperature daily and the room has never let me forget it
how cold is too cold, can it actually freeze in a normal fridge
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 6.8follow up buy a thermometer. mine reads 3.1 on the door and two degrees lower at the back
not the freezer
light exposure matters much less than temperature for these. i still keep them in the carton
i left it out overnight by accident, bin it or use it
test it

two to eight
flying with vials, hand luggage or checked
[edited]a liquid cold pack tells you it was above freezing, not that your vial cooked
gel packs
hand luggage
cold pack arrived completely liquid, does that mean anything
my fridge is running at 6.2, is that out of range
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct
