DOCUMENTATION

Certificate of Analysis (COA)

A COA is useful only when it clearly relates to the specific product and lot being reviewed. This guide explains what to check and how to request available batch documentation.

Match the lot

Compare product name, SKU, and lot number on the document with the material and its packaging.

Read the method

Look for the method, reported result, units, date, and stated limitations.

Keep records together

Store documents with the product record, receipt date, and relevant laboratory notes.

COA review checklist

  • Product identity and SKU are consistent.
  • The lot identifier matches the material.
  • The document names the method and reports results clearly.
  • Dates, units, and scope are understandable.
  • The document does not imply conclusions beyond the reported result.

Request available records

Contact support with the product name or URL, SKU, order reference if applicable, and lot number. Documentation availability depends on the product and batch.

What a COA does not establish

A COA is a record with a defined scope. It is not, by itself, proof of regulatory approval, clinical safety, effectiveness, sterility, or suitability for a particular experiment.
