Product Overview
This UltraDry™ iodine sphere formulation delivers 99.998% purity on a metals basis, engineered for applications demanding ultra-low moisture content. The -10 mesh spherical morphology ensures uniform particle distribution and consistent reactivity, eliminating variability in experimental results. The proprietary UltraDry™ treatment process removes surface-bound water and volatile impurities, making these spheres particularly suitable for hygroscopic reaction environments where trace moisture could compromise outcomes. The high assay purity (99.998%) minimizes metallic contaminants that could interfere with sensitive analytical techniques or catalytic processes. Packaged under inert conditions to preserve purity, these spheres maintain their specifications through extended storage periods. The material’s physical stability prevents agglomeration, ensuring accurate dispensing and reproducible performance across multiple experimental runs.
FAQs
1. What makes UltraDry™ iodine spheres different from standard iodine crystals?
The UltraDry™ treatment removes adsorbed moisture and volatile impurities, reducing water content to levels undetectable by standard Karl Fischer titration. Standard iodine often contains 0.1-0.5% residual moisture.
2. Can these spheres be used directly in anhydrous solvent systems?
Yes, the UltraDry™ grade is specifically processed for compatibility with anhydrous conditions. Pre-drying is typically unnecessary, though some protocols may require additional solvent purification steps.
3. What is the typical shelf life when stored properly?
When kept in the original sealed container under inert atmosphere, the spheres maintain their 99.998% purity specification for 24 months from the date of manufacture.
4. Are there any known compatibility issues with common lab materials?
The spheres are chemically stable with glass, PTFE, and most stainless steel alloys. Avoid prolonged contact with aluminum or copper, as halogen-induced corrosion may occur.
5. How does the -10 mesh size affect handling compared to finer powders?
The spherical -10 mesh particles (approximately 2mm diameter) minimize dust generation during weighing and transfer, reducing inhalation risks and material loss compared to powdered iodine forms.
