Quality Control

Our Libramycin A is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and pharmaceutical applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable to guarantee reliable quality and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or an inert atmosphere.
