Quality Control

Our Potassium Dithionite is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, impurity profiles, and physical characteristics. Our quality management system is designed to meet the rigorous demands of industrial and specialty chemical applications.

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 and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to minimize exposure to moisture and air. Keep away from heat, sparks, and open flame. Separate from oxidizing agents and strong acids.
