Compact Ultrasonic Disperser for Nanomaterials, up to 700 ml

Compact Ultrasonic Disperser for Nanomaterials, up to 700 ml

The SCIENTZ-750F is a high-power ultrasonic disperser from the SCIENTZ-F series. It uses ultrasonic cavitation to disperse materials in liquid–liquid, solid–liquid and gas–liquid systems. With 750 W (1–100%) of adjustable ultrasonic power, a Ø10 mm dispersing head and a processing capacity of 10–700 ml, it outperforms conventional dispersion methods and is particularly effective for nanomaterials.

Beyond dispersion, the instrument is used for cell lysis, emulsification, mixing, dissolving, defoaming, cleaning and acceleration of chemical reactions in biochemistry, microbiology, food science, pharmaceutical chemistry and materials research.

Key Features

• High output power – powerful ultrasonic output for demanding dispersion tasks
• Omnidirectional dispersing head – unique gourd-shaped head emits both lateral and longitudinal waves for uniform energy distribution
• Uniform results – dispersed particles show a narrow size distribution and slow sedimentation
• Flexible parameters – ultrasonic time and power continuously adjustable with good stability
• Selectable modes – pulsed and continuous operation with a test function
• 7-inch touch screen and electric lifting table
• Safety – time, temperature and overload alarms; soundproof box included

Working Principle

The generator converts mains power into a high-frequency electrical signal that drives a piezoelectric transducer. The resulting mechanical vibration is amplified by a titanium alloy horn and transmitted into the liquid at the probe tip. Rapidly alternating pressure cycles create cavitation bubbles that grow and collapse, generating intense local shear forces and micro-jets. These forces rupture cell walls and membranes, break up agglomerates and accelerate mass transfer and chemical reactions.

Applications of the SCIENTZ-750F Ultrasonic Disperser

• Dispersion of nanomaterials such as carbon nanotubes, graphene and silica
• Coatings: dispersion of titanium oxide, iron oxide, carbon black, fluorescent and photosensitive materials in water or solvents
• Biopharmaceuticals: dispersion of injectable drugs and vaccine preparation
• Cosmetics: emulsification of wax and paraffin, dispersion of micro-particles in detergents, shampoos and toners
• Food engineering: dispersion of milk powder and of raw materials in sauce production
• Cell lysis, mixing, dissolving, defoaming and acceleration of chemical reactions
