Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We implement strict in-process controls and final batch analysis to guarantee consistent purity and performance. Certificates of Analysis (COA) detailing key specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
