Rotor mills with variable speed and large sample volumes
The new generation of rotor mills SR 300 and SK 300 has been greatly improved with regard to performance, handling and flexibility, says the manufacturer. The speed of the rotor beater mill SR 300 has been substantially increased and can be set between 3,000 and 10,000 revolutions per minute (rpm), thus allowing for optimum adaptation to application requirements. It is therefore ideally suited for use in pharmaceutical and food laboratories. The new cross beater mill SK 300 now also operates with higher speed, which can be set from 2,000 to 4,000 rpm. Both mills can be equipped with an optional cyclone, which improves material discharge, particularly for very fine particle sizes, and provides additional cooling of the sample. — Retsch GmbH, Haan, Germany
