At WellChain, every batch is released with third-party Certificates of Analysis (COAs). We verify identity, purity percentage, appearance, and related impurities before listing a product. All products are sold strictly for Research Use Only (RUO).
Purity Workflow
- Batch Sampling – Each lot is assigned a batch ID and retained sample.
- Independent Testing – Third-party analysis confirms identity and purity.
- COA Release – We attach the COA to the product page (PDF download)
