Bacteriostatic Water 10ml

Bacteriostatic Water (10ml) – Sterile Diluent for Laboratory Reconstitution

Bacteriostatic water is a sterile, USP-grade diluent commonly used in laboratory settings for reconstituting lyophilized (freeze-dried) compounds. Unlike standard sterile water, it contains a small amount of benzyl alcohol, which acts as a bacteriostatic preservative, inhibiting the growth of bacteria across multiple uses from the same vial.

Composition and Function

Each 10ml vial contains water for injection combined with 0.9% benzyl alcohol. The benzyl alcohol content differentiates this product from plain sterile water, allowing a single vial to be accessed multiple times over a limited period without significant risk of microbial contamination, provided proper aseptic technique is followed during each withdrawal.

Laboratory Applications

In research contexts, bacteriostatic water is primarily used as a diluent to reconstitute lyophilized powders into solution form for further experimental use. Precise reconstitution volumes are important for maintaining accurate concentration calculations across research batches, supporting reproducibility in comparative studies.

Storage and Handling

Unopened vials should be stored at room temperature, away from direct light. Once opened, vials are typically kept refrigerated between 2°C and 8°C, and used within the timeframe recommended by standard laboratory protocols to preserve the integrity of the diluent and any reconstituted compound.
