Quality Control

Our Pentaethylene Glycol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for demanding industrial and research applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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 area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality, especially after opening the original container. Keep away from strong oxidizing agents.
