Quality Control

Our Dichlorodifluoromethane is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as purity, moisture content, and non-condensable gases. Our quality systems are designed to meet the exacting standards required for industrial and technical applications, ensuring product performance and supply chain integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, open flames, and incompatible materials. Due to its highly volatile and gaseous nature under standard conditions, cylinders must be secured upright and handled with appropriate pressure-rated equipment. Recommended storage temperature is below 30°C (86°F).
