Quality Control

Our Potassium Trifluorohydroxyborate 99.99% is manufactured under controlled conditions and undergoes rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and impurity profiles. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance protocols.

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 sealed under dry, inert conditions to prevent decomposition. Keep away from incompatible materials such as strong acids.
