Highlights from this day
- impersonator_ip — lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear 21:43
- sharps_comedy — hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct nobody here can tell you a vial is safe. we can tell you… 21:49
- sharps_comedy — for flying, hand luggage every time. the hold is not temperature controlled the way people assume, ask me again in a month 21:55
- steady_state_sue — how cold is too cold, can it actually freeze in a normal fridge 22:04
- nausea_window — buy a thermometer. mine reads 4 on the door and two degrees lower at the back, someone check my working 22:42

nobody here can tell you a vial is safe. we can tell you what has and has not survived for us
for flying, hand luggage every time. the hold is not temperature controlled the way people assume, ask me again in a month
buy a thermometer
i keep everything at the back of the middle shelf, never the door
how cold is too cold, can it actually freeze in a normal fridge
🧊1🤝1
what temperature does a domestic fridge door actually swing to
not the door
a few hours at room temperature is almost certainly nothing. a week is a different conversation
for the archive i log the fridge temperature daily and the room has never let me forget it
is there a difference in stability between the compounds
*Medutest not the other one
do i need to worry about light exposure or is that overthinking
[edited]parcel sat in a hot mailbox for 3 hours, is it dead
do you log the fridge temperature or is that too far
buy a thermometer. mine reads 4 on the door and two degrees lower at the back, someone check my working
my fridge is running at 3.1, is that out of range
two to eight degrees. most domestic fridge doors are not in that range and people do not check
hand luggage
is a five pound fridge thermometer actually worth it
two to eight
freeze thaw cycling is the risk, not one freeze. that is my read of it anyway, happy to be corrected
