Highlights from this day
- deadspace — 10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100 18:38
- deadspace — took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience 18:40
- mag_citrate — if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way 19:21
- mag_citrate — genuine question is it worth buying a 3ml syringe for the diluent or is the insulin one fine 19:22

10mg vial
+ 1.0ml -> 10.0 mg/ml 0.5mg = 5u 1mg = 10u
+ 2.0ml -> 5.0 mg/ml 0.5mg = 10u 1mg = 20u
+ 2.5ml -> 4.0 mg/ml 0.5mg = 12.5u (dont)
+ 5.0ml -> 2.0 mg/ml 0.5mg = 25u 1mg = 50utook me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience

not sterile water
anyone worked out a recon volume that puts 0.5mg on a round unit mark
how do you all measure a half unit, or do you just not
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way
