What a COA is

A Certificate of Analysis (COA) is the documentation issued for a specific production lot. It lets a laboratory tie the product in hand to its lot record for traceability and record keeping.

Record the lot number and COA reference in your lab records.

How to look up your COA

  1. Find the lot number printed on the vial label or carton.
  2. Enter the lot number in the lookup below. It opens the supplier COA lookup in a new tab.
  3. Keep the COA with the records for that lot.

COA lookup is hosted by our supplier at researchh2o.com. If your lot is not found, contact support with the lot number.
