Bacteriostatic Water
About Bacteriostatic Water
Bacteriostatic Water is sterile water preserved with 0.9% benzyl alcohol, which prevents bacterial growth and allows the vial to be used multiple times without contamination. Hospira is one of the most trusted names in pharmaceutical-grade injectable solutions, and their bacteriostatic water is the go-to choice for researchers reconstituting lyophilized (freeze-dried) peptides. Each 30ml vial provides plenty of solution for multiple reconstitutions, making it both practical and cost-effective.
Mechanism of Action
Lyophilized peptides are shipped as a dry powder to preserve their integrity during storage. Before use in research, they need to be dissolved ("reconstituted") in a sterile liquid. Bacteriostatic water does this job perfectly — the water dissolves the peptide evenly, while the 0.9% benzyl alcohol preserves the solution and prevents microbial contamination between uses. This makes it far safer for repeated use compared to plain sterile water.
Research Highlights
