Retsch Mortar Grinder RM 200, 230 V, 50 Hz, (please order mortar and pestle separately)

Not rated yet

Mortar grinders are suitable for reproducible sample preparation for subsequent analysis within the framework of quality assurance and GLP as well as for the preparation of prescriptions and formulations. Samples that are difficult to comminute can be successfully processed in mortar grinders by heating or cooling them, or by using grinding aids.

Function Principle


The RM 200 comminutes, mixes and triturates by pressure and friction. The function of the scraper is to feed the material into the area between the mortar and pestle. This forced feed ensures that the whole of the sample is continuously subjected to the grinding and trituration process and is also intensively mixed. The pestle is not located in the centre of the mortar but is offset; contact with the rotating mortar and the sample causes it to rotate automatically. The necessary grinding pressure is achieved by the weight of the pestle itself combined with the adjustable spring pressure acting on its axis.
