Quality Control

Our Sodium is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Quality is verified through a series of analytical tests, including assay by titration and analysis of key metallic impurities. While we offer standard technical and reagent grades, production can be aligned with specific customer requirements. A Certificate of Analysis (COA) documenting all relevant specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive nature, sodium must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, well-ventilated area, away from moisture, acids, and oxidizing agents. Recommended storage temperature is 15-25°C. The container must be kept tightly sealed to prevent contact with air and moisture, which can lead to oxidation or hazardous reactions.
