A Certificate of Analysis lists the batch number, HPLC purity result, benzyl alcohol concentration, pH, endotoxin level, and sterility status for the specific batch shipped, not a generic product sheet.
The batch number on the COA should match the batch number printed on the vial label, allowing research teams to trace their specific unit back to its exact manufacturing and testing record.
The HPLC section confirms purity and benzyl alcohol concentration, while the LAL endotoxin section confirms the batch falls below the research-grade threshold of 0.1 EU/mL.
Renew Lab Group issues a batch-specific COA with every order, rather than a generic lot certificate, so documentation always matches the physical vial received.
