Product Overview
This UltraDry™ barium chloride delivers exceptional purity at 99.998% (metals basis), specifically engineered for applications demanding ultra-low moisture content. The anhydrous form eliminates hydration variability, ensuring consistent performance in critical reactions where water interference could compromise results. Its high assay purity minimizes trace metal contaminants that might affect sensitive analytical techniques or synthesis pathways. The fine crystalline structure provides excellent solubility in polar solvents while maintaining stability under standard laboratory conditions. Packaged under inert atmosphere to preserve its dry state, this reagent is particularly valuable for preparing anhydrous reaction systems or as a precursor in specialized inorganic syntheses. The product’s rigorous quality control ensures batch-to-batch consistency, with residual moisture levels maintained below detectable thresholds for most analytical methods. Its non-hygroscopic nature when properly stored makes it ideal for long-term laboratory inventory without degradation concerns.
FAQs
1. What distinguishes UltraDry™ barium chloride from standard anhydrous grades?
The UltraDry™ designation indicates additional processing steps to achieve moisture levels significantly below typical anhydrous specifications, often measured in low ppm ranges rather than percentage points. This makes it suitable for applications where even trace water would be problematic, such as certain organometallic reactions or ultra-sensitive analytical procedures.
2. Can this product be used directly in aqueous solutions without pre-drying?
While the product is packaged as UltraDry™, any exposure to ambient humidity during handling will begin hydration. For aqueous applications requiring precise barium concentrations, we recommend dissolving in pre-dried solvents or using freshly opened containers to minimize moisture uptake before solution preparation.
3. What storage conditions maintain the UltraDry™ properties long-term?
Store unopened containers in a desiccator with active desiccant at room temperature, protected from light. Once opened, reseal immediately under dry nitrogen or argon if possible. Avoid storage in standard refrigerators unless using vacuum-sealed secondary containment, as frost-free cycles can introduce moisture.
4. Are there compatibility issues with common laboratory plastics?
Barium chloride solutions are generally compatible with PTFE, PP, and HDPE containers. However, prolonged contact with some polycarbonates or acrylic materials may cause stress cracking, particularly at elevated concentrations. For long-term storage of solutions, we recommend using borosilicate glass or dedicated chemical-resistant plastics.
5. How does the particle size distribution affect its use in different applications?
The fine crystalline powder form offers rapid dissolution rates for solution-based applications while providing sufficient surface area for solid-state reactions. For applications requiring specific particle size ranges, such as certain catalytic systems, additional sieving may be necessary to achieve optimal performance characteristics.
