Structure of an ultrasonic homogeniser
Conversion of the electrical voltage supplied by the generator into mechanical oscillations of the same frequency.
Ultrasound generator (control module)
Conversion of recorded low-frequency mains voltage of 50 or 60 Hz into a high-frequency voltage of 20 kHz. Control and display of all
Process parameters and procedures.
Step and booster horns
They amplify the vibrations coming from the ultrasonic transducer. The amplification level of the amplitude depends on the design.
They transmit the mechanical vibrations into the sample. The radiating surface is only at the tip, not at the sides. A high amplitude means a particularly intensive sonication. Due to their geometry, some sonotrodes can achieve multiple amplitude amplification. The sonotrodes thus achieve the highest ultrasound power densities in liquids.
Ultrasonic homogenisers for versatile applications
Certain substances can be specifically destroyed, lengthy procedures can be accelerated, the result of many reactions is improved. In the sample to be sonicated, particle sizes can be achieved not only in the μm, but also down to the nm range! BANDELIN supports you with its many years of know-how in the field of ultrasonic homogenisers in finding the solution for your special application. SONOPULS homogenisers with amplitude control 10-100 % and actual value display, pulsation, AMPLICHRON® circuit (guarantees constant amplitude independent of changing conditions), integrated timer, remote controllable.
We will be happy to provide you with loan units for practical testing.
