About Bacteriostatic Water
Bacteriostatic water is sterile water that contains 0.9% (9 mg/mL) benzyl alcohol. The benzyl alcohol does not sterilize the solution, but it inhibits the growth of most bacteria, which allows the same vial to be accessed repeatedly.
This distinguishes it from sterile water without preservative, which is single-use once opened. Because benzyl alcohol can interact with some materials, the choice of diluent should follow the documentation for the material being reconstituted.
Research context
In the laboratory, bacteriostatic water is used as a diluent for reconstituting lyophilized peptides when a multi-use vial is needed. Some peptides dissolve better in other solvents, such as dilute acetic acid or plain sterile water.

Bacteriostatic Water: frequently asked questions
What is the difference between bacteriostatic water and sterile water?
Both are sterile. Bacteriostatic water adds 0.9% benzyl alcohol to inhibit bacterial growth after the vial is opened; plain sterile water has no preservative and is single-use.
Which Bacteriostatic Water presentations are listed?
2 presentations are listed: 3 mL (WA3), 10 mL (WA10). Each is packed 10 vials per box, and every presentation has its own specification page and product code.
