Quality Control

Our Dowex Optipore L-493 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against critical parameters including particle size distribution, moisture content, specific surface area, and pore volume to meet the defined specifications. A Certificate of Analysis (COA) documenting these results is provided with every shipment. Our quality protocols are designed to support applications in regulated environments.

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). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture uptake, which can affect performance. Keep away from incompatible materials.
