Certificate of Analysis

Bacteriostatic Water with a Lot-Specific COA

A lot-specific COA is a Certificate of Analysis issued for one individual production lot — not a generic sample document — reporting that lot's own test results for sterility (USP <71>), endotoxin (USP <85>), benzyl alcohol assay, pH, and particulates. Because each lot is tested separately, only a lot-specific COA proves the vial in your hand was tested. BAC Water Depot publishes a lot-specific COA for every lot, tested by independent third-party laboratories, and a scannable QR code on each vial opens that exact lot's CoA.
