Verification
If you received a product bearing a SteriGenix Certificate of Analysis, you can verify its authenticity by entering the batch identifier. Each batch we analyze is tracked under a unique identifier assigned at sample receipt.

Clients request a submission number and ship samples via prepaid label. Minimum sample size varies by assay.
Standard turnaround for single-parameter assays is 3–5 business days. Full release panels run 5–7 days.
Results are delivered as signed PDF. Each certificate is retrievable publicly via its batch identifier.
In their words
"Turnaround was actually 4 days, not the promised 5 — and the chromatograms were the cleanest I've seen from any contract lab. Switched our entire purity panel to SteriGenix."
Dr. M. Ortega
Director of Quality, peptide research supplier
"We needed a third-party LAL on a recalled batch and they had results in 72 hours with full method documentation. Saved a customer relationship."
J. Whitman
Operations Lead, contract formulator
"The /verify portal cut our customer-service tickets in half. Buyers stopped asking for COAs — they just look them up."
