What Is Bacteriostatic Water?
Bacteriostatic water (also known as bac water or bacterialstatic water) is sterile water containing 0.9% benzyl alcohol. This preservative inhibits bacterial growth, making it ideal for reconstituting lyophilised (freeze-dried) peptides for research use. Unlike plain sterile water, bacteriostatic water allows multi-dose access over a 28-day period when stored correctly.

How to Reconstitute Peptides with Bac Water
Reconstituting peptides with bacteriostatic water is straightforward for laboratory research:
- Wipe the peptide vial stopper with an alcohol swab
- Draw the calculated volume of bacteriostatic water into a sterile syringe
- Inject the bac water slowly down the inside wall of the peptide vial
- Do not shake — gently swirl or let it dissolve undisturbed
- Store reconstituted peptides at 2-8°C for up to 28 days

Bacteristatic Water vs Sterile Water — What's the Difference?
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, preventing bacterial growth for up to 28 days after opening. Sterile water for injection has no preservative and must be used immediately. For peptide research requiring multiple access over time, bacteriostatic water is the standard choice. Bacteristatic water and bacterialstatic water are common misspellings — the correct term is bacteriostatic water.
