Quality Control

Every batch of Clearfil Photo Posterior is manufactured under strict quality management systems. Our products undergo rigorous quality testing to ensure compliance with industry standards for purity, performance, and consistency. Certificates of Analysis (COA) detailing specific batch results for identity, assay, and impurities 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants or an inert atmosphere.
