Quality Control

Our Copper(2+) Sulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, heavy metal content, and physical properties. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing assay results and confirming compliance with relevant industrial or agricultural grade standards. Customized quality parameters can be established to meet specific customer 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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture and caking. Keep away from incompatible materials.
