What is BAC Water?
Bacteriostatic Water for Injection (BAC Water) is sterile water containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth, making the solution safe for multi-dose use over an extended period - a critical property when working with reconstituted peptides in a research setting.

Why it matters for peptide research
Lyophilized (freeze-dried) peptides must be dissolved in a sterile liquid before use. Plain sterile water is single-dose only - once opened, microbial contamination risk rises sharply. BAC Water's benzyl alcohol preservative extends the usable life of the reconstituted vial, making it the standard diluent in peptide research.
Reconstitution basics
The volume of BAC Water added to a lyophilized vial determines the final concentration. For example, adding 2 mL to a 10 mg vial yields a concentration of 5 mg/mL (5,000 mcg/mL). Use the PharmaPep dose calculator to work through the arithmetic for your specific vial and dose.
Presentation
Each vial contains 30 mL of bacteriostatic water (0.9% benzyl alcohol). The multi-dose vial is compatible with standard research protocols requiring repeated draws.
Storage
Store at room temperature (15–30 °C), away from light. Do not freeze. Once the vial septum has been punctured, follow the storage and discard schedule specified in your research protocol.
