Description
Bacteriostatic Water is a specialized, sterile, and non-pyrogenic aqueous solution formulated with 0.9% (9 mg/mL) benzyl alcohol. In laboratory and biochemical research, it serves as the standard diluent for the reconstitution of lyophilized peptides and proteins. The inclusion of benzyl alcohol acts as a bacteriostatic preservative, effectively inhibiting the growth of most potentially contaminating bacteria. This preservative allows the solution to be utilized for multiple withdrawals from the same container within a 28-day period, provided aseptic techniques are maintained. It is a critical component for ensuring the stability and integrity of sensitive molecular compounds during experimental preparation.

Handling & Storage
To maintain the preservative efficacy and sterility of the solution, please follow these laboratory guidelines:
- Storage: Store at controlled room temperature (20°C to 25°C / 68°F to 77°F). Do not freeze.
- Stability: Once the vial is accessed (the seal is pierced), it should be used within 28 days. Discard any remaining solution after this period to ensure bacteriostatic integrity.
Note: Inspect the vial before use; the solution should be clear and free of particulate matter.
