Bacteriostatic Water (BAC Water)

Bacteriostatic Water (BAC Water) is a sterile, purified water solution formulated with 0.9% benzyl alcohol as a bacteriostatic preservative. It is a standard solvent in research laboratory environments, used for the dissolution of lyophilized peptides and other biochemical compounds where sterile, contamination-controlled solution preparation is essential.

Research background

BAC Water has been widely referenced in peptide research workflows as the solvent of choice for reconstituting lyophilized compounds. The inclusion of 0.9% benzyl alcohol has been studied for its capacity to inhibit bacterial proliferation in aqueous solutions, supporting sample integrity across repeated-use protocols. Its application is documented across biochemical and peptide-based research settings where sterility and solution stability are critical parameters.

Presentation & variants

• 10 ml vial – Suited for higher-volume reconstitution protocols or extended research workflows requiring multiple draws.
• 3 ml vial – Well-suited for small-scale or single-compound reconstitution applications.

Handling & use

BAC Water is supplied as a clear aqueous solution in a sterile vial, ready for use as a reconstitution solvent. When dissolving a lyophilized peptide, add an appropriate volume of BAC Water directly to the peptide vial. Gently swirl — do not shake — to achieve complete dissolution. All handling should be conducted under aseptic conditions to preserve solution integrity.

Storage & stability

Unopened vials should be stored at room temperature and protected from direct light. Once the vial has been accessed, store refrigerated and handle under sterile conditions. Observe standard laboratory practices for solution shelf-life following first use.

A batch-specific Certificate of Analysis (CoA) is included with every order.
