Quality Control

Our Perfluorodiethyl Ether is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Production adheres to relevant ISO 9001 standards, and material is analyzed against rigorous internal specifications. Key parameters including purity, non-volatile residue, water content, and acidity are verified. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 15-25°C.
