Quality Control

Our Arsenate products are manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with each shipment to guarantee compliance with your specifications and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
