Impact and shear forces
In a variable speed high-speed rotating crusher, the sample is crushed by the shear force between the high-speed rotating rotor edge and the screen mesh.

work quickly
Variable speed high-speed rotating crusherPULVERISETTE 14The classic model is equipped with a more powerful frequency converter, ensuring that the motor output power matches the type of sample being ground. Your advantage: Faster sample processing.

efficient cooling
FRITSCHProduct specific：PULVERISETTE 14The classic and clever air circulation channel ensures continuous airflow to cool the rotor, motor components, and samples in the collection tray. At the same time, the large exhaust fan blows cold air into the instrument through a filter, generating positive air pressure to prevent dust from entering the instrument from the ambient air.

Extremely time-saving: No tools are required, just a few steps are needed to quickly replace the grinding kit, ensuring simple and quick cleaning of the grinding kit.
Equipped with stainless steel wear-resistant rotors with smooth surfaces, making cleaning simple and fast!
Prevent contamination: There is a wear-resistant labyrinth disk between the grinding chamber and the drive motor.
Equipped with a membrane keyboard and an ergonomic control panel, the operation panel features a carefully designed LED display screen that can display speed and motor load, and can sound an alarm in case of extreme temperature and overload.

Multiple combinations of a grinding machine
Variable speed high-speed rotating crusherPULVERISETTE 14The standard configuration of the classic model includes a collection tray and a collection tray cover, so in order to use the instrument, you also need to order a rotor (rotary blade), a sieve, an impact ring, or a needle shaped insert - choose grinding accessories according to your specific application! To meet your needs,PULVERISETTE 14The various designs, materials, and additional accessories of the classic model include rotors and screens for you to choose from.
