What bacteriostatic water is
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic agent, which allows multiple withdrawals from a single sealed vial under laboratory conditions.
Why it matters for concentration math
The volume of solvent added to a lyophilized vial determines the resulting concentration in mg/mL. Adding 2mL to a 10mg vial yields 5mg/mL; adding 5mL to the same vial yields 2mg/mL.
Handling in the laboratory
Supplied in 10mL vials. Keep the stopper intact and swab before each withdrawal per standard practice.

Frequently asked
How is it different from sterile water?
Sterile water contains no preservative and is generally treated as single-use; bacteriostatic water contains benzyl alcohol, which inhibits bacterial growth in a multi-withdrawal vial.
