60 mg vial BAC Water Calculator
Worked example
Worked example: a default of 2 mL gives 30 mg/mL in a 60 mg vial (60 mg / 2 mL). To reach another concentration, divide the vial mass by it: water volume = 60 mg / target concentration. Change the target concentration to recalculate.

A desired concentration takes priority; leave it empty to use target amount and units instead.
How it works
Water volume = vial mass / target concentration: 60 mg / 30 mg/mL = 2 mL. The 2 mL shown is a default; change the target concentration to recalculate. Any volume above the 3 mL vial capacity is flagged.
Frequently asked questions
How many mL of bacteriostatic water give 30 mg/mL in a 60 mg vial?
Divide the vial mass by the concentration you want: 60 mg / 30 mg/mL = 2 mL. A default of 2 mL gives 30 mg/mL; change the target concentration to recalculate.
Is 2 mL of water more than a 3 mL vial holds?
Yes. 2 mL is within the 3 mL vial capacity used by default; the calculator flags any volume above it.
How much water would a 60 mg vial need at 1 mg/mL?
60 mL (60 mg / 1 mg/mL), which exceeds the 3 mL vial capacity, so a higher concentration is needed.
