Quality Control

Our Triple Dye is manufactured under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent staining performance, purity, and absence of interfering contaminants. Certificates of Analysis (COA) documenting identity, strength, and performance are available upon request to support your quality assurance and regulatory compliance needs.

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 after each use to prevent absorption of atmospheric moisture, which can affect performance.
