Variable Speed Rotor Mill Pulverisette 14 Premium

The Variable Speed Rotor Mill Pulverisette 14 Premium is a versatile, powerful mill for the fast grinding of medium-hard, brittle as well as fibrous materials and temperature sensitive samples.

The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 premium line offers impact, shearing and cutting comminution in one instrument with a higher performance, better cooling and is significantly quieter than comparable instruments.

Pleasantly quiet operation We have incorporated special design to ensure that it is considerably quieter than comparable instruments.

Significantly better cooling The strong airflow produced by the motor, an ingenious air routing, as well as special cooling fins on the rotors further intensify cooling. Your advantage: melting or sticking is greatly reduced, even with temperature-sensitive samples. The cooling function can easily be further enhanced by utilizing an optional Cyclone separator.

High-speed motor with ceramic bearings The heavy-duty motor and especially durable ceramic bearings ensure a particularly high impact and rotor speed with an extra powerful 22,000 rpm. Your advantage: finer results in shorter times.

AutoLOCK grinding chamber As soon as you have set the grinding parameters and started the grinding, the AutoLOCK grinding chamber closes itself tightly and safely. The grinding starts only when all the parts are fully and correctly inserted and the instrument‘s lid is properly locked. Your advantage: absolutely safe operation with a complete safety lock.

Intelligent control The integrated Intelligence-Safety-Control-System automatically checks the grinding set components for complete and correct insertion (collecting vessel with lid, rotor and labyrinth disk). Even the Vibratory Feeder LABORETTE 24 is monitored.

Fast and easy cleaning The Clean Design makes the cleaning of your mill as easy as possible. All the surfaces are designed to be extremely dirt-resistant and easy to clean, and every surface which comes into contact with the samples can be sterilised. All parts that need regular cleaning, like funnel, collecting vessel with lid, rotor, sieve ring and labyrinth disk, can be removed with a single motion without tools.

A high-speed rotor (up to 22,000 rpm – impact speed 111m/s – 400km/h) with sharped ribs crushes the sample by impact force. In addition, the sharp-edged teeth and the sieve insert reduce the sample by shearing. The sample is placed under stress in the last milling stage by friction between the rotor and the sieve insert. Ground material is
