What Is BAC Water?
Bacteriostatic Water for Injection is sterile water preserved with 0.9% benzyl alcohol. The benzyl alcohol acts as a bacteriostatic agent, inhibiting the growth of most bacteria and allowing the solution to be used multiple times from the same vial — a critical advantage in research workflows where a single peptide vial may be accessed repeatedly.
Why It Matters for Peptide Research
Lyophilized peptides are highly sensitive to contamination and degradation. Using non-sterile or improperly preserved water can compromise your sample integrity, skew your results, and waste expensive reagents. BAC Water provides:
- Extended vial usability — multiple draws without contamination risk
- Stable pH — minimizes peptide degradation during reconstitution
- Sterile filtration — reduces particulate matter that can interfere with assays
- Consistent concentration — precise volumes (10 mL and 30 mL) for accurate dosing calculations
Choosing the Right Pack Size
Whether you're running a short pilot study or managing a high-throughput lab, having the right quantity on hand reduces waste and keeps your workflow uninterrupted. Insulfine BAC Water is available in flexible pack sizes — from 3-packs for smaller projects to 12-packs for ongoing research programs.

Best Practices for Reconstitution
- Allow the lyophilized peptide to reach room temperature before opening.
- Add BAC Water slowly along the side of the vial — never inject directly onto the powder.
- Gently swirl (do not shake) until fully dissolved.
- Store reconstituted peptides at 2–8°C and use within the recommended timeframe.
