Ultrasonic Homogenizers for Liquid Processing
Hielscher ultrasonic devices are in use worldwide as laboratory mixers, high shear mixing equipment, full-size in-line homogenizers or particle mills. The applications include mixing, dispersing, particle size reduction, extraction and chemical reactions. We supply to various industry segments, such as nano-materials, paints & pigments, food & beverage, cosmetics, chemicals and fuels.

Hielscher offers a wide range of ultrasonic lab homogenizers (50 to 400W) to homogenize samples in beakers, test tubes or vials. Flow cells and flask adapters allow for more complex setups in the laboratory. For the sonication of closed vials, we offer the VialTweeter.
Bench-top homogenizers (0.5 to 2.0kW) are used for application research, scale-up work, pilot studies, process optimization or smaller batch processing. These programmable ultrasonic devices can be combined with flow cell reactors and pumps for in-line processing.
For high volume in-line processing or batch processing, we offer high-power ultrasonic probes (4 to 16kW). In commercial installations, these can run in clusters to process several hundred tons per hour. Sanitary designs, and multi-feed flow cells are avaible to adapt to your processing needs.
While the scale-up of a process from the laboratory or bench-top level to full production is the most critical and hardest step for other mixing technologies, it is most simple with Hielscher ultrasonic equipment. This is because; during scale up we do not change any of the driving parameters, such as amplitude or pressure.
Ultrasonic batch mixing works well for volumes of up to 100L for some purposes, however ultrasonic in-line mixing using flow cell reactors and a feed pump is the more effective solution. In a flow cell the ultrasonic power is highly concentrated on a small volume resulting a more uniform processing and better product quality. A back pressure valve can be used to increase the pressure in the flow cell. This intensifies the sonication significantly resulting in higher hydraulic shear.

Improved Digital Control
Our new devices come equipped with enhanced digital controls, such as touch screen, SD-card protocoling, temperature control and LAN interface for browser control. No software installation needed.
High Viscosity Slurries
Our bench-top and industrial homogenizers can process viscous slurries of up to 250,000 centipoise. For viscosities higher than 2,000 cPs we recommend the use of flow-cells with progressive cavity pumps for better coupling.
Easy-to-Clean / CIP
Hielscher ultrasonic mixers are available with sanitary fittings for easy access and cleaning. The ultrasonic cavitation assists clean-in-place procedures (CIP) – it is an extremely powerful ultrasonic cleaner in place.
