Bacteriostatic Water – Laboratory Grade USP

Bacteriostatic Water (BAC Water, 0.9% Benzyl Alcohol) is a laboratory-grade sterile aqueous diluent formulated for bench-scale peptide reconstitution, method development, and solvent-system studies. This USP-grade water contains 0.9% (v/v) benzyl alcohol as a preservative agent to inhibit bacterial growth in multi-dose research applications.

Research Applications:

• Peptide and protein reconstitution parameter optimization
• Solvent effect studies on peptide solubility and stability
• Concentration range determination for stock solution preparation
• Vial and stopper material compatibility testing
• Preservative impact assessment (BAC water vs. sterile water controls)
• Bioburden control studies in multi-dose vial systems
• Analytical method development (HPLC/LC-MS baseline characterization)
• Sample preparation matrix for peptide quantification assays
• Recovery and carryover studies in analytical workflows
• Storage and handling variable optimization (freeze-thaw tolerance)
• Container-closure integrity testing

Specifications:

• Composition: USP Water for Injection + 0.9% (v/v) Benzyl Alcohol
• Sterility: Sterile, non-pyrogenic
• pH: 5.0-7.0
• Preservative: 0.9% Benzyl Alcohol (antimicrobial agent)
• Available volumes: 3mL, 10mL, 30mL in sealed vials
• Storage: Room temperature (20-25°C), protect from light
• USP Grade quality standards

Important Notes:

• Verify compatibility with target peptides and analytical matrices prior to use
• Record lot/batch numbers in laboratory notebooks for reproducibility
• Single-use only in sterile research applications
• Not suitable for neonatal research models (benzyl alcohol sensitivity)

For laboratory research use only. Not for human consumption.
