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

Highlights from this day
- gall_bladder_gav — my rule is one concentration for everything so i never have to think about it at 7am 18:40
- oasis_ola — genuine question if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration, thats one data point 19:28
- gall_bladder_gav — is the meniscus reading actually a real source of error or am i overthinking 19:33
foam is bad
weighing the vial before you reconstitute is the only way to catch an underfill
it should be completely clear with no floaters. cloudy means stop
thats 5mg/ml
✅1
*that should say weekly
it foamed. is it ruined
is there any reason not to just always use 2ml
i was wrong about this last year: it is fine to draw cold, it just stings more going in
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way
check your maths
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
the jewellery scale is a good habit but calibrate it, they drift badly
[edited]bac water
label the vial
aim the diluent at the glass wall, not at the powder. it goes in gentler
do i swirl for a specific length of time or just until its clear
is it worth buying a 3ml syringe for the diluent or is the insulin one fine
round numbers
i have never once regretted using a rounder number and a slightly bigger volume
my rule is one concentration for everything so i never have to think about it at 7am

nope, redo it
a slightly collapsed cake is cosmetic. a puddle in the bottom is not
label the date too. you will not remember which vial is which by week 32
clear or bin it
U-100 syringe: 1 unit = 0.01 ml
10u = 0.10 ml
25u = 0.25 ml
50u = 0.50 ml
100u = 1.00 ml
mg drawn = ml drawn x mg/mlgenuine question if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration, thats one data point

how do you all measure a half unit, or do you just not
too dilute imo
