Product Overview
Lithium bromide hydrate in Puratronic™ grade offers exceptional purity at 99.995% (metals basis), making it a critical reagent for applications requiring minimal trace metal contamination. This hydrated crystalline solid is produced under stringent quality controls to ensure consistent performance in sensitive laboratory procedures. The high assay value guarantees reliable stoichiometry in reactions, while the controlled hydration level maintains stability during storage and handling. Its low impurity profile—particularly for alkali, alkaline earth, and heavy metals—reduces interference in spectroscopic, chromatographic, and electrochemical analyses. The material’s hygroscopic nature necessitates proper storage conditions to preserve its integrity. Designed for researchers and chemists who demand ultra-pure reagents, this grade is particularly suited for advanced synthesis, catalyst preparation, and as a calibration standard in instrumental techniques. The Puratronic™ designation signifies adherence to rigorous purity standards, ensuring reproducibility in high-stakes experimental workflows.
FAQs
1. What is the difference between Puratronic™ and standard-grade lithium bromide hydrate?
Puratronic™ grade undergoes additional purification steps to achieve 99.995% metals basis purity, with significantly lower trace metal impurities compared to standard grades, which typically range between 98-99%. This makes it suitable for applications where metal contamination could skew results, such as in semiconductor fabrication or trace analysis.
2. Can this product be used directly in anhydrous reactions without further drying?
No, this is a hydrated form and contains water molecules as part of its crystalline structure. For anhydrous applications, the material must be thoroughly dried under vacuum or using a desiccant like phosphorus pentoxide, followed by storage in an inert atmosphere to prevent rehydration.
3. What are the primary storage requirements to maintain its purity?
Store in a tightly sealed container under dry, inert conditions (e.g., nitrogen or argon) to prevent moisture absorption. Keep away from direct light and heat sources, and avoid exposure to air for prolonged periods, as it is highly hygroscopic. Desiccant packs in the storage container can help maintain low humidity.
4. Is this compatible with glassware, or does it require special containment?
Lithium bromide hydrate is compatible with borosilicate glass, though prolonged contact with highly concentrated solutions may etch the surface. For long-term storage or reactions, consider using PTFE-lined containers or high-density polyethylene (HDPE) bottles to minimize potential leaching or corrosion.
5. Are there lower-purity alternatives available for general lab use?
Yes, standard ACS-grade lithium bromide hydrate (typically 99% purity) is available for routine applications where ultra-high purity is not critical. These alternatives are cost-effective for educational labs, qualitative analysis, or processes tolerant to minor impurities.
