Description
Bacteriostatic Water is regarded as an essential element in peptide research workflows. This specialized solution blends ultra‑pure water with benzyl alcohol to establish conditions that suppress bacterial growth while preserving the stability of dissolved compounds. The inclusion of 0.9% benzyl alcohol is carefully optimized to deliver antimicrobial protection without compromising the integrity of most research materials. Thanks to this precise balance, bacteriostatic water has become the preferred standard for reconstituting lyophilized peptides, ensuring sterility and reliability across experimental applications.

Restrains bacterial proliferation (bacteriostatic) rather than eliminating cells (bactericidal).
Broad Spectrum
Active against a wide range of common laboratory contaminants.
pH Stability
Preserves antimicrobial efficacy across diverse pH conditions.
Peptide Compatibility
Non-reactive
Does not interact with most peptide structures
Integrity Preservation
Supports peptide stability during storage periods.
Repeated Access
Enables multiple withdrawals without introducing contamination.
Research Highlights
Bacteriostatic water provides a range of vital functions within laboratory studies:
Peptide Handling
Main role in peptide studies:
• Resolubilizes lyophilized peptides while preserving molecular integrity
• Retains biological activity of delicate compounds
• Ensures precise dilution and dosing accuracy
• Broad compatibility with most peptide formulations
Preservation Strategies
Extended stability for laboratory materials:
• Supports storage of reconstituted peptides for prolonged periods
• Protects against microbial contamination during storage
• Maintains sterility across repeated withdrawals
• Minimizes waste compared to single‑use solutions
Research Compliance
Meeting laboratory quality benchmarks:
• USP‑certified water guarantees consistency
• Low endotoxin levels suitable for sensitive assays
• Verified sterility for reproducible outcomes
• Documented quality control for regulatory assurance
Usage Guidelines
Best practices in experimental settings:
• Apply aseptic technique for every withdrawal
• Store reconstituted peptides under recommended conditions
• Clearly label vials with reconstitution date
• Discard immediately if turbidity or particulates are observed
Possible Research-Related Effects
Essential considerations for effective use of bacteriostatic water:
Thermal Requirements
Controlled Storage: Keep within specified temperature range to preserve sterility
Compatibility Assessment
Peptide Verification: Confirm that benzyl alcohol does not interfere with peptide formulations
Shelf‑Life Monitoring
Expiry Control: Track expiration dates and discard once validity has lapsed
Volume Management
Accurate Dilution: Determine correct reconstitution volumes for precise dosing
Proper management of bacteriostatic water safeguards the integrity of studies and supports reproducible results.
