Quality & Testing
Certificate of Analysis
Every batch we sell is tested by an independent third-party laboratory and shipped with a Certificate of Analysis you can verify. Most bac water on the market ships with no batch testing at all — we publish ours. The certificate below covers the current batch; every lot has its own permanent, verifiable page.
