Quality Control

Our Hemalin is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling via techniques such as HPLC, NMR, and IR spectroscopy. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent exposure to atmospheric moisture.
