Product Overview
Cesium chloride (CsCl) of 99.999% purity (trace metal basis) is an ultra-high-grade reagent designed for demanding laboratory applications where trace metal contamination must be minimized. This extra pure form ensures exceptional consistency in density gradient centrifugation, a critical technique in molecular biology for separating nucleic acids, proteins, and subcellular components. The crystalline powder dissolves readily in water, forming clear solutions ideal for creating precise density gradients. Its high purity eliminates interference from metallic impurities, making it indispensable for sensitive analytical procedures, including spectroscopy and chromatography. The compound’s hygroscopic nature necessitates careful handling and storage in a desiccated environment to maintain its integrity. This grade is particularly valued in research settings where reproducibility and accuracy are paramount, as even minute impurities can compromise experimental validity. The absence of detectable trace metals ensures compatibility with high-resolution instrumentation, reducing background noise in analytical measurements. Whether used in preparative or analytical workflows, this cesium chloride variant delivers reliable performance, supporting high-throughput applications without compromising on quality.
FAQs
1. What is the primary use of 99.999% cesium chloride in laboratories?
This grade is primarily used for density gradient centrifugation due to its ability to form stable gradients, enabling the separation of biomolecules like DNA, RNA, and proteins with high precision.
2. How should cesium chloride be stored to prevent contamination?
Store in a tightly sealed container under dry, inert conditions, preferably in a desiccator, to avoid moisture absorption and degradation of purity.
3. Is this cesium chloride compatible with standard lab glassware?
Yes, it is compatible with borosilicate glass and most plastic labware, but avoid prolonged contact with metals to prevent contamination.
4. What alternatives exist for density gradient applications if cesium chloride is unavailable?
Potassium bromide or iodixanol can be used as alternatives, though they may require adjustments to gradient protocols due to differences in density and solubility.
5. Does this product contain any additives or stabilizers?
No, this is a pure crystalline form without added stabilizers or preservatives, ensuring minimal interference in sensitive applications.
