Why use bacteriostatic water?
Bacteriostatic water's benzyl alcohol preservative allows a single vial to be safely accessed multiple times over a period of weeks, rather than being limited to one draw like plain sterile water. For laboratory work that involves repeated reconstitution or dilution from the same vial, that preservative is the difference between a vial that lasts and one that needs to be discarded after a single use.
