Certificate archive

COA

A certificate of analysis belongs to one batch. It names the identity, the HPLC result, and the storage condition. When the desk has that file, the concierge sends it before the order is confirmed.

Open a product to read the specs. To receive the certificate for the batch that will ship, use online consultation and name the product. The file is a laboratory record for that lot, not a medical opinion.
