Description

Clerici'S Solution CAS NO 61971-47-9 is a high-density aqueous solution primarily composed of thallium formate and thallium malonate, used as a heavy liquid for mineral separation and density determination. This specialized reagent is critical for precise density gradient separations in geological and materials science laboratories. It is an essential tool for geologists, mineralogists, and researchers involved in the analysis and beneficiation of mineral ores, industrial minerals, and synthetic materials.

Application

• Mineral Separation (Sink-Float Analysis): Primary application for separating mineral mixtures based on specific gravity differences in geological samples.
• Density Gradient Centrifugation: Used to create density gradients for the separation of fine particles, synthetic materials, or biological components in research.
• Ore Dressing and Beneficiation Studies: Aids in laboratory-scale testing to determine the theoretical recoverability and processing methods for various ores.
• Petrographic Analysis: Assists in the identification and characterization of rock-forming minerals and synthetic crystalline materials.
• Heavy Liquid for Micromounting: Used in the preparation of microscopic mineral specimens for detailed examination.
• Academic and Industrial Research: Serves as a standard heavy liquid in university geology departments and industrial R&D labs for material property analysis.

Quality Control

Our Clerici'S Solution is manufactured and tested to ensure consistent density, purity, and performance for critical separation tasks. Each batch is controlled against strict internal specifications to guarantee reliability for geological and industrial applications. A Certificate of Analysis (COA) detailing density, assay, and clarity is provided with every shipment to ensure traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its composition, this solution is light-sensitive and should be kept in its original amber glass bottle or an equivalent light-protected container. Keep away from incompatible materials.
