What is bacteriostatic water?
Bacteriostatic water (BAC Water) is sterile water containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits microbial growth, so a solution reconstituted with it can be used for up to 28 days when stored refrigerated at 2–8°C — unlike plain sterile water without a preservative, which is suitable only for a single withdrawal after opening. For in-vitro laboratory research use only (Research Use Only).

Frequently asked questions about bacteriostatic water
What is bacteriostatic water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. It inhibits microbial growth, allowing longer usable stability of reconstituted peptide solutions.
Why bacteriostatic water instead of plain sterile water?
The benzyl alcohol content inhibits bacterial growth, so peptides reconstituted with it remain stable for up to 28 days at 2–8°C. Plain sterile water without a preservative is suitable for single use only.
Which size fits which vial size?
The 3ml format is the common standard size for typical lyophilised research preparations in the milligram range; the 10ml format suits preparations with a larger solvent requirement. Exact solvent planning is the responsibility of the receiving research lab.
Is BAC Water included with peptide orders?
Yes. Every NovaCell peptide order already includes free bacteriostatic water in the matching size. The vials sold here are for larger projects or as a reserve.
How is unopened BAC Water stored?
Unopened vials can be stored at room temperature (15–25°C). Stability and handling protocols after opening are subject to the receiving laboratory's internal QA system.
