Highlights from this day
  • spreadsheet_stu — while im here weighing the vial before you reconstitute is the only way to catch an underfill 13:52
  • spreadsheet_stu — if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way 14:06
  • spreadsheet_stu — benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically label the date too. you will not remember which vial is which by week 15 14:08
  • spreadsheet_stu — is it normal for the cake to look slightly collapsed on one side 14:09
  • VialBot — Verification log updated: GL Biochem — evidence added, status unchanged. 18:03

FT

you can absolutely just always use 2ml, and honestly most of us should

SS

benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically
label the date too. you will not remember which vial is which by week 15

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 = 50u

is it normal for the cake to look slightly collapsed on one side

30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

FT

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

TW

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

TT

for the archive 20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
