Highlights from this day

night_pin — if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way 20:27
night_pin — i use bac water even for a single-use vial because it stings less, which is not the reason it exists 21:13
brisbane_bac — bacteriostatic water for anything multi-use. sterile water has no preservative in it at all, i have it written down somewhere 21:17
dorm_fridge — for the archive one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that 21:42

if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way

not sterile water

aim the diluent at the glass wall, not at the powder. it goes in gentler

weighing the vial before you reconstitute is the only way to catch an underfill

dead space

💀1

how much do i lose to dead space with a 29G pin

i use bac water even for a single-use vial because it stings less, which is not the reason it exists

label the date too. you will not remember which vial is which by week 23

bacteriostatic water for anything multi-use. sterile water has no preservative in it at all, i have it written down somewhere

my rule is one concentration for everything so i never have to think about it at 7am

does benzyl alcohol matter if im finishing the vial in one go

for the archive one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that

do i swirl for a specific length of time or just until its clear

anyone got a photo of what a properly dissolved vial looks like

update from 16 months ago: switched to a single concentration and have not miscalculated since

the last few units are a real loss. i accept it rather than tilting the vial and drawing air

label the vial
