Quality Control

Our Sodium Fluoride Hydrofluoride is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee consistency and traceability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature and classification as a fluoride/strong alkali, the container must be kept tightly sealed to prevent moisture absorption and degradation. Store separately from strong acids.
