Product Overview
Calcium chloride UltraDry™ (99.99% metals basis) is an ultra-high-purity anhydrous salt engineered for critical moisture control in laboratory and industrial settings. This grade is processed to eliminate trace water content, ensuring maximum hygroscopicity and efficiency as a desiccant. The anhydrous form rapidly absorbs atmospheric moisture, making it indispensable for drying gases, solvents, and maintaining dry environments in sealed systems. Unlike standard calcium chloride, the UltraDry™ variant undergoes rigorous purification to remove metallic impurities, delivering consistent performance in sensitive applications where residual moisture or contaminants could compromise results. Its granular or powdered form allows flexible deployment—whether in desiccator chambers, drying tubes, or as a reagent in synthesis. The material’s high solubility in water and alcohols further enhances its utility in liquid-phase drying processes. Stored under inert conditions, this product retains its ultra-low moisture specification, ensuring long-term reliability for experiments requiring absolute dryness.
FAQs
1. What is the difference between UltraDry™ calcium chloride and standard anhydrous calcium chloride?
The UltraDry™ grade is purified to 99.99% metals basis, eliminating trace impurities and residual water that standard anhydrous grades (typically 97-99%) may contain. This makes it superior for moisture-sensitive applications where even minimal contamination could affect outcomes.
2. Can this product be used for drying organic solvents like ethanol or acetone?
Yes, UltraDry™ calcium chloride is highly effective for drying organic solvents due to its strong affinity for water. However, it forms soluble complexes with alcohols, so filtration is required post-drying to remove the resulting calcium chloride-alcohol adducts.
3. How should I store UltraDry™ calcium chloride to maintain its purity?
Store the product in a tightly sealed container under inert gas (e.g., nitrogen or argon) to prevent moisture absorption. Avoid exposure to ambient air during handling, and use a desiccator for partial quantities.
4. Is this grade compatible with halogens or oxidizing agents?
While calcium chloride itself is chemically stable, UltraDry™ grade should not be mixed with strong oxidizers (e.g., potassium permanganate) or halogens in concentrated forms, as impurities in commercial reagents could catalyze unwanted reactions. Always verify compatibility in your specific system.
5. What alternatives exist if I need a non-hygroscopic drying agent?
For applications where hygroscopicity is undesirable, consider molecular sieves (3Å or 4Å) or silica gel. These alternatives offer controlled moisture absorption without the risk of deliquescence associated with calcium chloride.
