Quality Control

Our Chlorophyll A is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopy. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and degradation. For long-term stability, keep the product in a freezer at -20°C. The container should be allowed to reach room temperature before opening to prevent condensation.
