As an accredited Osmium Tetroxide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Osmium Tetroxide, 5 grams, packaged in a sealed amber glass vial, within a protective secondary container, labeled Sigma Aldrich. |
| Shipping | Osmium Tetroxide is shipped in tightly sealed, corrosion-resistant containers, usually ampoules or vials, within secondary protective packaging. It is classified as a highly toxic, oxidizing, and volatile substance, requiring specialized labeling and handling under hazardous material transport regulations. Shipment is strictly regulated via ground or air, following UN 2471 guidelines. |
| Storage | Osmium Tetroxide (Sigma Aldrich/Merck/TCI Chemical) should be stored in tightly sealed glass containers, in a cool, well-ventilated, and secure chemical storage cabinet, preferably under inert atmosphere. Keep away from light, heat, and organic/combustible materials. Store separately from acids, bases, and reducing agents. Use secondary containment to prevent spills, and restrict access to trained personnel due to its high toxicity and volatility. |
