Bacteriostatic Water – 10 mL

Bacteriostatic Water (10 mL) is a sterile, non‑pyrogenic aqueous solution containing 0.9% benzyl alcohol as a preservative. It is widely used in laboratory environments for the dilution, preparation, and reconstitution of lyophilised research materials where sterility and multi‑use stability are required.

This solution is supplied in a Type I borosilicate glass vial to maintain chemical integrity and ensure compatibility with sensitive laboratory workflows.

Areas of Research Interest
Reconstitution Studies
Used as a solvent for lyophilised peptides and analytical reference materials under controlled aseptic technique.

Formulation & Method Development
Supports preparation of aqueous solutions for stability testing, assay development, and laboratory formulation studies.

Preservative Mechanism Research
The 0.9% benzyl alcohol content is commonly examined for its antimicrobial inhibitory properties during repeated withdrawals.

These characteristics make Bacteriostatic Water a standard utility reagent across biochemical, analytical, and pharmaceutical research settings.
