Product Overview
This high-purity selenium shot is produced in amorphous form with a particle size range of 2-6mm (0.08-0.2 inches), meeting the stringent Puratronic grade specification of 99.999% purity on a metals basis. The material undergoes rigorous purification processes to eliminate trace impurities, making it suitable for applications where contamination control is critical. The shot form provides convenient handling and precise dosing for laboratory procedures. Selenium in this purity grade exhibits consistent chemical behavior and reliable performance in sensitive analytical techniques. The amorphous structure ensures uniform reactivity, while the controlled particle size distribution enhances process reproducibility. This product is packaged under inert conditions to prevent oxidation and maintain its ultra-high purity during storage and transportation. The Puratronic certification guarantees the absence of metallic contaminants that could interfere with experimental results or device performance.
FAQs
1. What is the typical shelf life of this selenium shot when stored properly?
When stored in its original packaging under dry, inert conditions away from light and moisture, this selenium shot maintains its specified purity for at least 24 months from the date of manufacture. The amorphous form is particularly stable compared to crystalline selenium.
2. How does the Puratronic grade differ from standard laboratory-grade selenium?
The Puratronic grade represents the highest purity level available for selenium, with a guaranteed 99.999% metals basis purity. This means the total metallic impurity content is limited to just 10 ppm, compared to standard grades which may contain 100-1000 ppm of impurities that could affect experimental outcomes.
3. Can this selenium shot be used directly for thin film deposition?
While the high purity makes it suitable for thin film applications, the 2-6mm shot size would typically require additional processing like thermal evaporation or sputtering. The material’s amorphous nature provides a consistent source for uniform film deposition when properly handled.
4. What precautions should be taken when handling this high-purity selenium?
Despite its amorphous form, selenium remains toxic and should be handled in a fume hood with proper PPE including gloves and eye protection. The material should be stored in a dedicated container to prevent cross-contamination with other lab chemicals.
5. Is this selenium shot compatible with standard laboratory glassware?
The material can be used with borosilicate glassware, though prolonged contact with moisture may lead to surface reactions. For long-term storage or sensitive applications, we recommend using PTFE or other chemically resistant containers to maintain purity.
