A Complete Guide to Buying Bacteriostatic Water for Research

What Is Bacteriostatic Water?

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative, designed for the multi-dose reconstitution of medications and research compounds. The preservative inhibits the growth of most bacteria, allowing safe repeated use.

Key Factors When Sourcing

• Purity: Look for USP-grade water for injection base.
• Preservative: Confirm the correct 0.9% benzyl alcohol concentration.
• Packaging: USP-grade borosilicate glass vials with proper seals.
• Documentation: A full Certificate of Analysis (COA) should always be available.
