What Is Bacteriostatic Water?
Bacteriostatic water is sterile water containing a small amount of benzyl alcohol (0.9%), a bacteriostatic preservative that inhibits the growth of bacteria within the vial. Unlike standard sterile water, which must be used immediately and discarded, bacteriostatic water can be accessed repeatedly over a period of up to 28 days after first puncture, making it the preferred diluent for multi-use research and laboratory applications.
It is the most commonly recommended solvent for reconstituting lyophilized (freeze-dried) peptides because benzyl alcohol is chemically inert with most research compounds and maintains long-term stability of the reconstituted solution under refrigeration.
Common Research Applications
- Reconstitution of lyophilized research peptides
- Dilution of laboratory compounds requiring a preserved aqueous medium
- Multi-day experimental protocols requiring repeated draws
- In vitro research and cell culture preparation
- General-purpose laboratory diluent
