Description
Bacteriostatic Water 10ml (BAC Water) – Sterile Reconstitution Diluent
Bacteriostatic water, commonly called BAC water, is sterile water for laboratory use containing 0.9% benzyl alcohol as a bacteriostatic preservative. The preservative suppresses bacterial growth inside the vial, which is why bacteriostatic water is the standard diluent for reconstituting lyophilized (freeze-dried) research peptides when a prepared solution will be drawn from more than once during a study.

Bacteriostatic Water vs. Sterile Water
Plain sterile water contains no preservative, so once its seal is punctured it is a single-use diluent. Bacteriostatic water’s 0.9% benzyl alcohol keeps the vial usable across multiple draws over a research timeline, which is why virtually all peptide reconstitution protocols specify BAC water rather than plain sterile water.
How Much BAC Water Do You Need?
The right volume depends on the peptide amount and the concentration your protocol calls for. Our free bacteriostatic water calculator gives the exact volume for any vial size, and the reconstitution calculator works out concentrations and unit measurements from there. New to the process?
