Quality Control

Every batch of Sodium-Difluoro(Oxalato)Borate is manufactured and tested under strict quality management protocols to ensure consistency and high purity for demanding electrochemical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay, moisture content, and ionic impurity levels.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and fluoride/strong alkali properties, this material must be stored in a cool, dry, and well-ventilated place. For long-term stability, store under an inert atmosphere (e.g., argon or nitrogen) in a desiccator at a controlled room temperature (15-25°C). Keep away from incompatible materials.
