Bacteriostatic Water 3mL is a sterile diluent composed of water for injection containing 0.9% benzyl alcohol as a bacteriostatic preservative. Supplied in a 3mL vial, it serves as a general-purpose reconstitution solvent for lyophilized research peptides and other water-soluble compounds handled in laboratory workflows. The 0.9% benzyl alcohol acts to inhibit the growth of common bacterial contaminants, which is what distinguishes it from single-use sterile water and makes it a practical reference solvent for protocols where a stock vial is accessed more than once.
As a reconstitution medium rather than an active reference compound, its role is functional: it returns a lyophilized powder to solution at a defined concentration while helping preserve the sterility of that stock across repeated withdrawals in cell-culture, preclinical, and in-vitro model work. Researchers select bacteriostatic water when a peptide stock must remain usable over a working period rather than being consumed in a single reconstitution.
Key research areas
