Bacteriostatic Water

BAC Water – Bacteriostatic Water

BAC Water, also known as Bacteriostatic Water, is sterile water containing benzyl alcohol, a preservative commonly used to help inhibit microbial growth within multi-use laboratory preparations. It is widely used in research settings for dissolving, diluting, and reconstituting lyophilized peptides, proteins, and other bioactive compounds.

The inclusion of benzyl alcohol helps maintain product integrity during repeated vial access, supporting stability and reducing the risk of contamination when handled correctly in a controlled laboratory environment. BAC Water is commonly paired with lyophilized peptide powders, allowing researchers to prepare solutions as required for experimental use.

At R&R Peptides, peptides are supplied as lyophilized powder to support maximum stability before reconstitution. BAC Water is supplied strictly for laboratory and research purposes only. It is not intended for human consumption, medical use, diagnosis, treatment, or prevention of any disease.
