Quality Control

Our Eicosatetraenoicacid is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including identity confirmation by FT-IR, purity assessment by GC or HPLC, and checks for peroxides and other oxidation products to ensure it meets the stringent requirements of research and production applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the sealed container to reach room temperature before opening to minimize moisture condensation. Keep away from heat and oxidizing agents.
