Overview
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol as a preservative, making it the standard reconstitution solvent for lyophilised research peptides. The benzyl alcohol preservative inhibits bacterial growth in the reconstituted solution, allowing for repeated use of a single vial over several weeks without contamination risk.
Nova Biolabs supplies 3ml BAC water vials from UK domestic stock, suitable for reconstituting all lyophilised peptides in our range.
It's easy to assume any water will do, but plain water — even sterile water for injection — has no preservative in it. Once a lyophilised peptide is reconstituted with plain sterile water, the vial has no protection against bacterial growth, so it should only be used immediately and discarded rather than stored. Bacteriostatic water's 0.9% benzyl alcohol content is specifically what allows a single vial to be punctured repeatedly over several weeks in a research setting, which is why it's the standard choice for multi-dose reconstitution rather than sterile water or saline.
Key Research Areas
Peptide Reconstitution
BAC water is the universal standard for reconstituting lyophilised research peptides for in vitro experimental use.
Multi-Use Vial Research
The 0.9% benzyl alcohol preservative allows repeated puncture and withdrawal from a single vial over 28 days, enabling serial dosing protocols in research settings.
Stability Studies
BAC water is used in comparative stability studies examining the shelf life of reconstituted peptides under various storage conditions.
Sterility Assurance
Produced under sterile manufacturing conditions, BAC water provides a contamination-free reconstitution environment critical for accurate research results.
