Quality Control

Our Staphyloxanthin is produced and handled under strict quality protocols to ensure batch-to-batch consistency and purity for research and development purposes. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below for long-term stability. This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
