As an accredited Sulfurous Acid factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Sulfurous Acid is packaged in a 500 mL amber glass bottle with a secure, chemical-resistant cap and clear hazard labeling. |
| Shipping | Sulfurous acid is shipped as a solution since it cannot be isolated in pure form. Transport must occur in corrosion-resistant, tightly sealed containers, preferably made of materials like glass or certain plastics, and stored in a cool, ventilated area. Proper labeling and compliance with hazardous material regulations are essential during shipping. |
| Storage | Sulfurous acid should be stored in tightly sealed, corrosion-resistant containers, away from heat, sunlight, and incompatible substances such as oxidizers and alkalis. Store in a cool, well-ventilated area to minimize decomposition and release of sulfur dioxide gas. Care should be taken to prevent exposure to moisture and to regularly check containers for signs of corrosion or leaks. |
