Quality Control

Our Silvercolloidal is produced under stringent quality management systems. Each batch is characterized for critical parameters including particle size distribution, concentration (ppm of Ag), zeta potential, and pH to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C). Do not freeze. The dispersion is light-sensitive; prolonged exposure to light may affect stability. Keep away from strong electrolytes and oxidizing agents.
