As an accredited Silicon Dioxide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging is a 500g white plastic bottle with a blue screw cap, labeled "Silicon Dioxide, SiO₂, Laboratory Grade." |
| Shipping | Silicon Dioxide is shipped in tightly sealed containers such as drums, bags, or bulk containers to prevent contamination and moisture absorption. Proper labeling and documentation are required. It is transported under normal environmental conditions, as it is non-hazardous, stable, and not classified as dangerous goods for shipping by land, sea, or air. |
| Storage | Silicon dioxide should be stored in a tightly closed container in a cool, dry, and well-ventilated area. Keep it away from incompatible substances, such as hydrofluoric acid. Protect from moisture and avoid generating dust. Ensure storage areas are labeled and comply with safety regulations. Maintain containers upright to prevent spills and only use containers made of compatible materials. |
