The RM 200 is the latest generation of the classic “RETSCH Mill” which replaced manual mortars and pestles more than 80 years ago. It is widely used for reproducible sample preparation in R&D, materials testing and especially in pharmaceutics and homeopathy. Many different materials can be easily and efficiently processed in wet or dry condition. The grinding sets of the RM 200 can be selected out of 7 different materials which allows for neutral-to-analysis sample preparation. The new generation of mortar grinders is exceptionally powerful, safe and easy to operate.
