About Prism H2O
Bacteriostatic water is sterile water with a small amount of benzyl alcohol, a preservative that limits bacterial growth, so one vial can be entered more than once. Prism H2O is Prism Labs’ bacteriostatic water for laboratory reconstitution: 0.9% benzyl alcohol in a 10 mL vial, with a certificate of analysis for every batch.
The official US label for Bacteriostatic Water for Injection describes a sterile, nonpyrogenic water containing 0.9% (9 mg/mL) or 1.1% (11 mg/mL) benzyl alcohol, added as a bacteriostatic preservative. Its pH is 5.7, within a range of 4.5 to 7.0.
