Quality Control

Our Cadmium Sulfate, Hydrate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications, including assay, heavy metal limits, and clarity of solution. A Certificate of Analysis (COA) detailing purity and test results is provided with every shipment to guarantee traceability and compliance with your quality 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or changes in composition.
