Cab-O-Sil® M-5 (Scintillation Grade)

Specifically purified and tested to eliminate background quenches and trace fluorescing contaminants, this scintillation-grade powder acts as an exceptional gelling and thixotropic agent. When added to liquid scintillation cocktails, it builds a reversible physical gel network that keeps insoluble, heavy, or particulate radio-labeled samples suspended uniformly without settling to the bottom of the vial. This ensures consistent 4π geometry for accurate radioactivity counting and maximum photon detection efficiency.

Key Functional Benefits:

• Optical & Scintillation Grade Purity: Meticulously processed to maintain high optical transparency in liquid cocktails, preventing background quenching and light absorption during luminescence assays
• Superior Particle Suspension: Forms a stable thixotropic gel matrix that holds particulate samples, soil suspensions, and insoluble radioactive precipitates uniformly in the counting zone
• High Surface Area Architecture: High specific surface area provides rapid dispersibility and effective viscosity control with minimal chemical loading required
• Chemically Inert Foundation: Pure amorphous synthetic silica structure remains non-reactive with most scintillators, fluors, organic solvents, and target solutes
