Quality Control

Our Eisenin is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, MS for identity confirmation, and stringent controls for residual solvents and heavy metals. Certificates of Analysis (COA) detailing all specifications are provided to ensure compliance with your research or cGMP guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under desiccant or inert atmosphere after opening to maintain stability and prevent degradation.
