What is a Certificate of Analysis?
A Certificate of Analysis (COA) is a laboratory document that verifies the identity, purity, and quality of a specific product batch. Each COA contains analytical results from laboratory testing that confirm the product meets the stated specifications. At Janera Science, every batch is accompanied by a lot-specific COA so researchers can independently verify the material they receive.
Janera Science is a research-use supplier built around clarity, structure, and measurable standards. We support laboratories, academic institutions, and professional researchers who require materials backed by documentation and defined quality controls.
Our focus is straightforward: consistent release criteria, transparent analytical data, and materials supplied within a framework designed to reduce uncertainty.
At Janera Science, quality is established through defined standards and documented verification.”

Our Third-Party Testing Process
Our Third-Party Testing Process
All products are tested by independent analytical laboratories to confirm quality and consistency. These tests typically include methods such as HPLC purity analysis and screening for contaminants such as endotoxins and heavy metals and sterility Via USP testing. Only batches that meet our quality standards are released and accompanied by a corresponding COA for transparency and verification.
