Quality Control

Our Zinc Chloride, Hydrated is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required chemical and physical specifications. We provide Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, heavy metal content, and loss on drying. Production can be aligned with various industry standards, including technical, reagent, and pharmaceutical grades, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or solution formation. Keep away from incompatible materials such as strong bases and oxidizing agents.
