Quality Control

Our Trisodium Arsenite is manufactured under strict quality protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed against stringent internal specifications, with comprehensive testing for identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Long-term storage under an inert atmosphere is recommended to minimize potential oxidation.
