Quality Control

Our Sodium Arsenate is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and purity. Each lot undergoes rigorous analytical testing, including assay and impurity profile analysis. A comprehensive Certificate of Analysis (COA) detailing purity, heavy metal content, and other critical parameters is provided with every shipment to support your quality assurance requirements.

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; containers must be kept tightly sealed to prevent absorption of atmospheric moisture and degradation.
