Quality Control

Our Ammonium Selenate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive (store away from light), so containers must be kept tightly sealed to prevent absorption of atmospheric moisture and degradation.
