Quality Control

Our Selenium75 is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analysis to verify isotopic enrichment and chemical purity, ensuring consistency for critical research applications. A detailed Certificate of Analysis (COA) is provided, reporting key parameters including isotopic abundance and trace metal content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, long-term storage under an inert atmosphere (e.g., argon or nitrogen) is recommended for optimal stability.
