Highlights from this day
- non_scale_win — 30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right, thats just me the jewellery scale is a good habit but calibrate it, they… 21:33

the jewellery scale is a good habit but calibrate it, they drift badly
one unit is 0.01ml

round numbers
lyophilised powder is far more robust than people think. it is the solution that is fragile
while im here bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
[edited]nope, redo it
ok so if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
quick one gross powder mass is not net peptide. water and counterion are in that number
a slightly collapsed cake is cosmetic. a puddle in the bottom is not
whats the smallest volume you would trust yourself to measure on a u100
do i swirl for a specific length of time or just until its clear

is it normal for the cake to look slightly collapsed on one side
sorry to jump in what do you do with the last 30 units when you cant draw them cleanly
coming back after 18 months, has the pinned recon volume advice changed
i keep a spare vial of bac water in the fridge purely so i never rush the maths
does temperature of the bac water matter at all
