BAC Water
A sterile, preservative-containing solvent used in research settings for the reconstitution and storage of lyophilized peptides.

What is Bac Water?
Sterile water containing 0.9% benzyl alcohol, used as a research-grade solvent for reconstituting lyophilized peptides. Its bacteriostatic properties inhibit microbial growth, allowing reconstituted solutions to remain stable and contamination-free for up to 28 days after first use.
