Quality Control

Our Calcium Hypochlorite Tetrahydrate, Reagent grade is manufactured under strict quality management protocols. Each batch is tested to ensure it meets the high-purity standards required for reagent and analytical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place away from heat, sparks, and open flame. Due to its hygroscopic and oxidizing nature, keep the container tightly sealed in a dry environment and separate from combustible materials, acids, and reducing agents. Recommended storage temperature: 15-25°C.
