Questions
Bacteriostatic Water (10 mL): common questions
What is bacteriostatic water?
Bacteriostatic water is sterile water with 0.9% benzyl alcohol added as a preservative. The benzyl alcohol keeps bacteria from multiplying in the vial, which is why it is sold as a multi-dose vial. Torrey Labs sells it in 10 mL vials for laboratory research use only.
What is in bacteriostatic water?
Two things: sterile water and benzyl alcohol at 0.9% (9 mg per mL). Nothing else is added.
What is the difference between bacteriostatic water and sterile water?
Sterile water has no preservative, so it is a single-use product: once a vial is opened, what is left is thrown away. Bacteriostatic water contains 0.9% benzyl alcohol, which lets the same vial be entered more than once. They are not interchangeable labels for the same product.
Does bacteriostatic water need to be refrigerated?
A sealed vial does not: store it at room temperature, as printed on its label. Follow the label for storage once the vial has been opened.
How long is bacteriostatic water good for?
Unopened, it is good until the expiry date printed on the vial. Once the stopper is first punctured, USP <797> gives a multi-dose vial a 28-day beyond-use date unless the maker states otherwise.
