Bacteriostatic Water

Description

Bacteriostatic Water – research-grade laboratory diluent

Bacteriostatic water is an aqueous diluent commonly formulated with 0.9% benzyl alcohol as a bacteriostatic preservative. The preservative helps inhibit bacterial growth within the container, making the preparation relevant to controlled laboratory procedures involving repeated withdrawals.

Within laboratory research contexts, bacteriostatic water may be used as a vehicle for dissolving or diluting compatible research materials. It does not contain an active peptide or research compound and should only be used where compatibility with the material being studied has been established.

Laboratory relevance of Bacteriostatic Water

Bacteriostatic water is commonly associated with:

• Controlled dilution of compatible laboratory materials
• Reconstitution of compatible research compounds
• Preparation of research solutions at defined concentrations
• Laboratory procedures requiring repeated vial withdrawals
• Vehicle-control and formulation-compatibility studies

Scientific and laboratory background

Commercial Bacteriostatic Water for Injection, USP is described as water for injection containing benzyl alcohol as a bacteriostatic preservative and supplied in a multiple-dose container. Common formulations contain 0.9% benzyl alcohol, equivalent to 9 mg/mL. The presence of a bacteriostatic preservative does not eliminate the need for appropriate aseptic laboratory technique.

Compatibility depends on the specific research material, concentration, formulation, storage conditions and experimental methodology. Some compounds may be incompatible with water or with solutions containing benzyl alcohol.
