Bacteriostatic Water

Product Overview

Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative agent, specifically formulated for use as a diluent in research laboratory settings. This essential laboratory supply is used for reconstituting lyophilized peptides, proteins, and other research compounds that require aqueous dissolution. Bacteriostatic Water is one of the most commonly used diluents in peptide research due to its ability to inhibit bacterial growth after initial puncture, allowing multiple withdrawals from a single vial while maintaining sterility.

NXTSTATE supplies Bacteriostatic Water manufactured under strict quality-controlled conditions, with each lot tested for sterility, endotoxin levels, pH, and benzyl alcohol concentration. Every vial ships with documentation confirming compliance with USP specifications for bacteriostatic water for injection.

Research Applications

Bacteriostatic Water serves as the preferred reconstitution vehicle for a wide range of lyophilized research compounds including synthetic peptides, recombinant proteins, and lyophilized hormones. The 0.9% benzyl alcohol preservative provides continuous antimicrobial protection, which is essential when researchers need to access reconstituted solutions over multiple experimental sessions spanning days or weeks. This eliminates the need to prepare fresh reconstitutions for each experiment, improving workflow efficiency and reducing compound waste.

In peptide research specifically, Bacteriostatic Water is preferred over normal saline or sterile water for injection when multi-dose reconstitution is required. The preservative agent prevents microbial contamination that could compromise experimental integrity, introduce confounding variables, or degrade sensitive peptide sequences. Researchers working with growth hormone releasing peptides, metabolic peptides, and regenerative peptides routinely rely on Bacteriostatic Water for consistent and reliable reconstitution results.

Quality Assurance

NXTSTATE Bacteriostatic Water is manufactured in facilities that adhere to Current Good Manufacturing Practice (cGMP) standards. Each production lot undergoes comprehensive quality control testing including sterility testing per USP Chapter 71, bacterial endotoxin testing per USP Chapter 85, particulate matter analysis per USP Chapter 788, and benzyl alcohol concentration verification by HPLC. Certificate of Analysis documentation accompanies every shipment, providing researchers with complete transparency into lot-specific testing results and compliance verification.

Usage Guidelines

When reconstituting lyophilized peptides, slowly inject Bacteriostatic Water along the inside wall of the peptide vial to minimize foaming and potential degradation. Allow the lyophilized material to dissolve gradually without vigorous shaking or vortexing. Gentle swirling may be used to facilitate dissolution. Once reconstituted, store solutions under refrigeration at 2-8 degrees Celsius and use within 28 days for optimal stability. Always swab vial stoppers with alcohol prior to needle insertion. Use appropriate aseptic technique during all handling procedures.
