UDS 751

Ultrasonic Desintegrator UDS 751 for dispersing solutions, emulsions and suspensions by focused ultrasonic

With the ultrasonic disintegrator UDS 751/UP 200S, ultrasound with very high power densities - up to 600 W/cm² - can be introduced into liquid media.
UDS 751 Ultrasonic Processor, front view Sonotrodes for the UDS 751 | UP 200S
The UDS 751, developed in cooperation with Hielscher GmbH, was replaced in mid-2006 by the UP 200S, which is identical in construction. With it, an extraordinarily wide range of laboratory and small-scale production tasks can be solved.

  • support of wet sieving

The ultrasonic disintegrator consists of a high-frequency generator, a transducer and a sonotrodes screwed to the transducer. The high-frequency generator converts the 50 Hz mains voltage into a 24 kHz high frequency voltage. The electrical energy is converted by the transducer into mechanical, vertical vibrations of the same frequency. The sonotrodes screwed to the transducer, which are designed as lambda/2 transducers and are made of highly elastic titanium alloys, amplify the vertical vibrations and transmit the ultrasonic energy with extremely high power densities into the liquids via their end faces. The resulting cavitation enables the wide range of applications to be solved in biology, medicine, chemistry, technology and other fields of application.
