Highlights from this day
how long after reconstituting before its actually dissolved
[edited]label the vial
weigh it first
can i add more bac water later to a vial ive already reconstituted

my rule is one concentration for everything so i never have to think about it at 7am
10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100
how do you all measure a half unit, or do you just not
whats the smallest volume you would trust yourself to measure on a u100
not sterile water
check your maths
thats the vacuum

if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
anyone got a photo of what a properly dissolved vial looks like

if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space

for the archive is it normal for the cake to look slightly collapsed on one side
clear or bin it
write the date on
*VendorInvestigate not the other one
aim the diluent at the glass wall, not at the powder. it goes in gentler
bac water
read it at eye level

my vial pulled the water in on its own, is that the vacuum or did i do something

label the date too. you will not remember which vial is which by week 16
i have never once regretted using a rounder number and a slightly bigger volume
the powder is stuck to the stopper, do i care
round numbers
bac water or sterile water for something im going into weekly for 6 weeks
quick one 5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose
10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100
anyone worked out a recon volume that puts 7.5mg on a round unit mark
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
