Quality Control

Our Polyglycine is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including determination of molecular weight distribution, purity assay, and residual solvent analysis. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize moisture absorption, which can affect product stability and performance.
