Sterile water for injection containing 0.9% benzyl alcohol as a bacteriostatic preservative. Used to reconstitute lyophilised research peptides for laboratory applications.
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is the standard diluent used to reconstitute lyophilised research peptides for laboratory use. Once reconstituted, peptides stored with bacteriostatic water typically retain integrity for up to 30 days under refrigeration.
Quantum Labs supplies bacteriostatic water as a research supply for use with our peptide catalogue. It ships from Australian stock alongside lyophilised peptide orders.
Research Mechanism
Benzyl alcohol provides bacteriostatic activity, allowing multi-dose reconstitution of lyophilised peptides while maintaining sterility under standard research conditions.
HPLC verified against a ≥99% purity specification. Independently tested by accredited third-party laboratories.
Bacteriostatic Water — frequently asked questions
What is bacteriostatic water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, used to reconstitute lyophilised research peptides. The benzyl alcohol prevents bacterial growth in multi-use vials.
How much bacteriostatic water do I need to reconstitute a peptide?
Volume depends on the peptide and the desired working concentration. A common starting point is 2-3 mL of bacteriostatic water per 5 mg vial, producing a working concentration that simplifies dose-volume calculations. Researchers should adjust volumes to their specific protocol requirements.
How long does a reconstituted peptide last?
Reconstituted peptides stored at 2-8°C in bacteriostatic water typically retain integrity for up to 30 days, depending on the specific compound. Avoid freeze-thaw cycles which can degrade peptide structure.
Can I use regular water instead of bacteriostatic water?
Sterile water without preservative produces single-use solutions only — bacterial contamination is rapid once the vial is breached. Bacteriostatic water with 0.9% benzyl alcohol is the standard diluent for multi-use research peptide reconstitution.
