Product Overview
Cesium bromide, UltraDry™ (99.9% metals basis) is a high-purity, anhydrous reagent designed for applications requiring minimal moisture interference. Its crystalline powder form ensures consistent performance in density gradient centrifugation, where precise buoyancy and separation are critical. The UltraDry™ grade guarantees low hygroscopicity, making it ideal for long-term storage without degradation. This compound is also widely used in optical applications due to its excellent transparency in the infrared spectrum, providing reliable results in spectroscopy and laser systems. The 99.9% purity level minimizes impurities, reducing background noise in sensitive experiments. Whether used in research or advanced analytical techniques, this cesium bromide variant delivers reproducibility and accuracy. Its stability under controlled conditions further enhances its suitability for high-precision laboratory work, ensuring that researchers and technicians achieve dependable outcomes without compromising on quality.
FAQs
1. What makes UltraDry™ cesium bromide different from standard grades?
UltraDry™ cesium bromide undergoes rigorous drying processes to eliminate residual moisture, reducing hygroscopicity and improving stability during storage and use. This ensures consistent performance in moisture-sensitive applications like density gradients.
2. Is this cesium bromide compatible with common organic solvents?
Yes, it dissolves readily in water and polar organic solvents such as methanol and ethanol, but its solubility in nonpolar solvents is limited. Always verify compatibility with your specific solvent system before use.
3. Are there alternatives to cesium bromide for density gradient centrifugation?
Alternatives include cesium chloride, iodixanol, and sucrose gradients, but cesium bromide is preferred for its higher density range and sharper banding resolution in DNA/RNA separations.
4. How should this product be stored to maintain its UltraDry™ properties?
Store in a tightly sealed container under inert gas (e.g., nitrogen or argon) in a desiccator. Avoid exposure to humid environments to prevent moisture absorption, which can alter its performance.
5. What is the typical shelf life of UltraDry™ cesium bromide when stored properly?
When stored under recommended conditions—away from moisture and light—the product retains its specified purity and performance for up to 24 months from the date of manufacture.
