Quality Control

Every batch of our phospholipids is produced under strict quality management systems. We provide comprehensive analytical documentation to ensure identity, purity, and consistency for your critical applications. Certificates of Analysis (COA) detailing specifications such as assay, fatty acid profile, and impurity limits are available for each lot. Our quality systems support compliance with cGMP and ISO standards for pharmaceutical and research use.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and hydrolysis. For long-term stability, the product should be kept desiccated. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation.
