This Model is a particularly sturdy machine, enabling optimal and perfectly reproducible grinding and dispersions to be obtained in the laboratory. The grinding is carried out by two ground glass discs. The fixed upper disc is the part of the system for adjusting operating force between 11 and 220 lbs. (5 and 100kg) and is fitted on a cranked arm to make it easier to open. The bottom plate rotates at 100 rpm. The movement is provided by a powerful geared motor system capable of carrying out tests under extreme conditions.

The whole grinder is built into a housing made of thick steel plates. One counter counts the number of revolutions and automatically stops the motor. Another shows the total after each test cycle.
