Quality Control

Our Tungstic Acid is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture. Separate from strong acids and strong bases.
