research monograph

what the literature shows.

A condensed monograph drawn from preclinical and clinical literature. Cited mechanisms, specifications and the research case for bac water.

01 · mechanism of action

Bacteriostatic water is sterile water for injection with 0.9 % benzyl alcohol added as antimicrobial preservative. In research it is the standard solvent for reconstituting lyophilized peptides and proteins. The benzyl alcohol inhibits microbial growth and enables multiple withdrawals from a vial over weeks without contamination risk. Unlike simple water for injection (WFI), BAC water remains sterile-usable for 28 days after vial puncture — crucial for protocols that require repeated withdrawals from the same vial unit.

02 · product specifications

Available in 3 ml and 10 ml vials. Sterile-filled, preserved with 0.9 % benzyl alcohol. Pharmaceutical grade, suitable for reconstitution of research peptides. Each vial is sealed with a rubber septum for aseptic withdrawal.

03 · research advantages

Industry standard for reconstituting research peptides. Multi-dose compatibility combined with the antimicrobial action of benzyl alcohol makes it the preferred solvent in peptide-based research protocols.
