How is the selenium powder packaged (bottles, pouches, etc.)?

Selenium powder is often supplied in different forms which rely on amount and use. For example, small amounts of selenium powder are usually sealed in air-tight glass or plastic containers that prevent moisture entry and contamination. In addition, selenium powder can be supplied in form of resealing pouches, drums or bags lined with materials that provide extra protection against air and moisture entry for larger supplies. Packaging plays an important role in keeping the selenium powder stable and uncontaminated during transport and storage.
