Product Overview
Lithium bromide, UltraDry™ grade, delivers exceptional 99.998% purity on a metals basis, making it the preferred choice for applications demanding ultra-low moisture and high chemical consistency. This crystalline powder is processed under stringent conditions to eliminate residual water content, ensuring reliability in hygroscopic-sensitive environments. Its high solubility in polar solvents and thermal stability allow for seamless integration into complex synthesis protocols without compromising reaction integrity. The UltraDry™ designation guarantees minimal hygroscopicity, reducing the risk of moisture-induced degradation during storage or handling. Ideal for advanced analytical techniques, this grade maintains consistent stoichiometry, critical for reproducible results in quantitative assays. The absence of metallic impurities ensures compatibility with high-sensitivity instrumentation, preventing interference in spectroscopic or chromatographic analyses. Packaged in airtight containers, it preserves its ultra-low moisture profile until use, eliminating the need for additional drying steps. Whether used as a reagent, catalyst, or standard, this lithium bromide variant meets the exacting requirements of modern laboratories where precision and purity are non-negotiable.
FAQs
1. What is the significance of the UltraDry™ label in this lithium bromide?
The UltraDry™ label indicates that this lithium bromide undergoes rigorous drying processes to achieve an ultra-low moisture content, typically below 50 ppm. This is critical for applications where even trace moisture can alter reaction outcomes or degrade sensitive materials. The packaging is also designed to maintain this dry state during storage and transport.
2. Can this lithium bromide be used directly in anhydrous solvent systems?
Yes, this grade is specifically formulated for anhydrous conditions. Its ultra-low moisture content ensures compatibility with anhydrous solvents like THF or diethyl ether without introducing water, which could compromise the reaction environment. However, always verify the solvent’s moisture specifications to ensure full compatibility.
3. How does the 99.998% metals basis purity compare to other lithium bromide grades?
The 99.998% metals basis purity means that metallic impurities are reduced to just 20 ppm, significantly lower than standard or even ACS-grade lithium bromide. This level of purity is essential for applications like semiconductor manufacturing, high-purity crystal growth, or as a standard in trace metal analysis where contamination must be minimized.
4. What precautions should be taken when storing this product to maintain its dryness?
Store the unopened container in a desiccator or a dry, inert atmosphere glove box to prevent moisture absorption. Once opened, reseal the container immediately using the provided airtight cap and store it with desiccant packs. Avoid exposure to ambient humidity, as lithium bromide is highly hygroscopic and can rapidly absorb moisture from the air.
5. Is this lithium bromide compatible with glassware, or are there material restrictions?
This product is compatible with standard borosilicate glassware, though prolonged contact with highly concentrated solutions may etch the glass over time. For long-term storage or reactions involving concentrated solutions, consider using PTFE-lined or polypropylene containers to prevent potential leaching or corrosion. Always rinse glassware thoroughly after use to avoid residue buildup.
