Quality Control

Our Atramycin B is produced and tested under stringent quality management systems to ensure it meets the exacting standards required for research and pharmaceutical applications. Each batch undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling via advanced techniques like HPLC and mass spectrometry. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
