Quality Control

Every batch of Prosil 28 is manufactured and tested under a rigorous quality management system to ensure it meets the high standards demanded by our global B2B clients. Our quality control protocols are designed to guarantee batch-to-batch consistency, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent degradation from atmospheric moisture. Keep away from heat and incompatible materials.
