Quality Control

Our Dodecaethylene Glycol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and performance. A Certificate of Analysis (COA) detailing key parameters such as assay, water content, and impurity profile is provided with each shipment and is available upon request.

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). This material is hygroscopic (moisture-sensitive) and should be handled in a dry atmosphere to prevent absorption of water. For long-term storage, consider using an inert gas blanket to minimize oxidation.
