RANTEK Ultra Centrifugal Mill is a high speed rotor mill with unmatched performance. 

It is used for the rapid size reduction of soft to medium-hard and fibrous materials. 
Because of the efficient size reduction technique ensures the gentle preparation of analytical samples in a very short time. 

The comprehensive range of accessories including a large variety of ring sieves and rotors as well as collection systems 
makes the Ultra Centrifugal Mill a versatile instrument that can be easily adapted to varying applications. 
The optional Vibratory Feeder is load-controlled via an interface and ensures a uniform grind at maximum output rate. 
When using a cyclone, the sample material is additionally 
cooled by the air stream and more rapidly discharged from the grinding chamber via the cassette pan with outlet. 
This effect can be increased by connecting a vacuum cleaner.
