Battery-Powered Portable Ultrasonic Homogenizer
The UP-250S is the battery-powered version of the UP-250 portable ultrasonic homogenizer. Its built-in lithium battery allows up to 4 hours of continuous operation without an external power source, making it an ideal sample preparation tool for field research, on-site testing and vehicle-based inspections – for example in mobile environmental protection and food safety monitoring laboratories.
Like the mains-powered model, the UP-250S is designed for small-volume, high-throughput work such as samples in 96-well plates or small tubes. It is used for emulsification, dispersion, homogenization, extraction, degassing, cleaning, preparation of nanomaterials and acceleration of chemical reactions.
Key Features
- Independent lithium battery – up to 4 hours of continuous operation without mains power
- Portable design – compact unit for field and mobile laboratories
- Selectable modes – automatic and manual operation, optional foot switch
- Flexible parameters – adjustable ultrasonic power and duration
- Safety – over-temperature alarm
- Easy operation – 4.3-inch touch screen
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.
