Quality Control

Our production of Ast 120 adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. The material is manufactured under controlled conditions and undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization. Certificates of Analysis (COA) documenting all test results are provided with each shipment to guarantee compliance with your specifications and industry standards.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which may affect product performance. Keep away from incompatible materials.
