Peripheral devices for sieving are commonly used to supply the energy necessary for the separation process. The use of electromagnetically created vibrations is typical for this.
Studies of microsieving have shown that in addition to the ultrasonic energy used for the process also the mechanical energy contributes to the microsieving process optimization in the form of horizontal vibrations. For this purpose Topas GmbH has developed the Electromagnetic Sieve Vibrator EMS 755. One important feature of this development was the simplicity of changing the sieves. At the stand the device can easily be positioned at any distance to the ground.
It is possible to use additional energy e.g. ultrasonic energy with the Ultrasonic Disintegrator UDS 751/UPS200S which can be mounted onto the stand too. Furthermore the EMS 755 can easily be used together with a standard wire cloth sieve to disperse dry powder systems (bulk analysis).
