Bacteriostatic water is a laboratory supply used to reconstitute lyophilized peptides for research.
Bacteriostatic water is sterile water containing a small amount of benzyl alcohol (typically about 0.9%), which inhibits the growth of microorganisms. In research settings it is the standard diluent used to reconstitute lyophilized (freeze-dried) peptides, allowing a dissolved solution to remain usable longer than with plain sterile water.
It is a handling supply rather than an active research compound. Correct reconstitution technique and storage help maintain the stability of the dissolved peptide preparation.
Standard diluent for dissolving lyophilized research peptides in the lab.
Benzyl alcohol inhibits microbial growth, extending usable solution life.
Reconstituted solutions are typically kept refrigerated at 2–8 °C.
A laboratory consumable used across peptide research, not an active.
The standard diluent paired with lyophilized peptides for reconstitution.
Water volume added sets concentration — the calculator does the math.

It is sterile water with a small amount of benzyl alcohol that inhibits microbial growth, used as the standard diluent to reconstitute lyophilized research peptides.
The benzyl alcohol helps keep a reconstituted solution usable longer by limiting microbial growth, which is useful when a vial is accessed multiple times in research.
The volume you add sets the concentration of the dissolved peptide. The Peptide Calculator converts vial size and water volume into units per syringe mark.
