As an accredited Sodium Dithionite factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging is a 25 kg white polypropylene bag, labeled "Sodium Dithionite," featuring hazard warnings and manufacturer details in bold print. |
| Shipping | Sodium dithionite should be shipped in tightly sealed, moisture-proof containers, away from heat, sources of ignition, and incompatible substances such as oxidizers and acids. It must be clearly labeled, handled as a hazardous material (UN 1929), and stored in a cool, dry, well-ventilated area during transport to prevent decomposition and fire risks. |
| Storage | Sodium dithionite should be stored in a cool, dry, and well-ventilated area, away from sources of moisture, heat, and incompatible materials such as acids and oxidizers. Keep the container tightly closed and protected from light to prevent decomposition. Avoid contact with air and water, as sodium dithionite is sensitive to humidity and may release sulfur dioxide gas on decomposition. |
