Bac-Water Manufacturer

MayMag Biologics Bac water manufacturer in the USA

The Science of Safety

Bacteriostatic Water for Injection (BWFI) is a crucial component in modern medicine, used to dilute or dissolve medications for injection. Unlike regular sterile water, bacteriostatic water contains exactly 0.9% benzyl alcohol, which acts as a preservative to halt the growth of most potentially contaminating bacteria. This allows vials to be safely re-entered multiple times for multi-dose applications.

Quality Control Assurance Framework at MayMag Biologics
