Bac-Water 30 ML

BAC water (short for bacteriostatic water) is sterile water for injection that contains a small amount of benzyl alcohol as a preservative—typically 0.9% (9 mg/mL), though some formulations use 1.1%.

The benzyl alcohol is bacteriostatic, meaning it inhibits bacterial growth (rather than killing bacteria outright). This allows the same vial to be entered multiple times with proper aseptic technique, unlike plain sterile water, which is usually intended for single use
