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, 500 mL, packed in an amber glass bottle with a tightly sealed cap, labeled with hazard warnings and CAS number. |
| Shipping | Sulfurous acid should be shipped in tightly closed, corrosion-resistant containers, protected from heat and sources of ignition. It must be transported under cool, dry conditions and labeled according to hazardous material regulations. Avoid contact with incompatible substances. Ensure containers are upright and securely fastened to prevent leakage or spills during transit. |
| Storage | Sulfurous acid should be stored in tightly sealed containers made of corrosion-resistant materials, such as glass or certain plastics, as it is highly unstable and decomposes easily. Keep it in a cool, well-ventilated area, away from direct sunlight and incompatible substances like oxidizers and bases. Ensure proper labeling, and avoid heat or sparks to prevent decomposition and release of toxic gases. |
