Quality Control

Our Azophenyl-Edta is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation (IR). A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee the material meets your research or process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
