Quality Control

Our Berthierine is sourced and processed to meet the exacting requirements of research and industrial applications. Each batch undergoes rigorous quality testing, which may include X-ray diffraction (XRD) for phase identification, chemical analysis for elemental composition, and particle size distribution. Certificates of Analysis (COA) detailing lot-specific results are available upon request to ensure full traceability and compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). As a fine mineral powder, it should be kept in a dry environment to prevent moisture absorption and caking.
