Why You Need Bacteriostatic Water
Using the right solvent for reconstitution is critical for accurate research results and safety.
Proper Reconstitution
Bacteriostatic water is the standard solvent for reconstituting lyophilized peptides, ensuring proper dissolution while maintaining compound integrity.
Contamination Prevention
The benzyl alcohol preservative prevents bacterial growth, making it safe for multiple withdrawals from a single vial unlike sterile water.
Cost Efficiency
The 28-day multi-use window means one vial of BAC water can be used across multiple reconstitutions, reducing waste and overall research costs.
Reliable Results
Consistent pharmaceutical-grade quality ensures your reconstitution process is standardized, leading to reproducible and reliable research outcomes.

Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth and allows for multiple uses over 28 days. Sterile water has no preservative and must be used immediately after opening.
Once the vial has been punctured, bacteriostatic water can be safely used for up to 28 days when stored properly. After 28 days, discard the vial and use a fresh one.
Store unopened vials at controlled room temperature (20-25°C / 68-77°F). After opening, you may store at room temperature or refrigerated. Keep away from direct sunlight.
Yes. Every batch is third-party tested with a Certificate of Analysis (COA) available. Our BAC water is manufactured under USP guidelines.
The amount varies depending on the peptide and your desired concentration. Common reconstitution volumes range from 1mL to 3mL per vial.
