What is bacteriostatic water?

Bacteriostatic Water for Injection (USP) is a sterile, multi-use reconstitution solvent containing 0.9% benzyl alcohol as a bacteriostatic preservative. Supplied in a 10ml vial, it is the standard solvent used to reconstitute lyophilised peptides. For professional laboratory research use only.

What is bacteriostatic water used for in research laboratories?

Bacteriostatic water is used to reconstitute lyophilised peptide compounds — dissolving the powder into a precise-concentration solution for in-vitro and preclinical research. The 0.9% benzyl alcohol preservative allows the same vial to be used for multiple reconstitutions over several days. It is not for administration to humans or animals.

How should bacteriostatic water be stored?

Store bacteriostatic water at room temperature (15-25°C), protected from direct light and kept in its sealed vial until first use. Unlike lyophilised peptides which require -20°C freezer storage, bacteriostatic water should not be frozen. Follow appropriate laboratory handling and safety protocols.

What is the shelf life of bacteriostatic water from HPLC Peps?

Each 10ml bacteriostatic water vial is supplied with a clearly marked expiry date. Once the vial seal is broken, the benzyl alcohol preservative keeps the solution bacteriostatic for approximately 28 days when stored correctly. Discard any unused solution after this window and follow appropriate laboratory disposal protocols.

Is bacteriostatic water for human or animal use?

No. Bacteriostatic water from HPLC Peps is supplied strictly for professional laboratory research use only. It is not for administration to humans or animals and is not a medicine. The benzyl alcohol preservative is not suitable for use in living subjects.
