Quality Control

Our Sodium Zirconyl Sulfate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as zirconium content, sulfate content, and impurity levels are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and caking.
