Mixer Mill MM 200  The mixer mill MM 200 is a laboratory "all-rounder". It has been developed specially for dry grinding of small amounts of sample. It can mix and homogenize a wide range of materials in only a few seconds. It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA recovery.
Application Examples
tissue, bones, hair, chemicals, drugs, coated and uncoated tablets, minerals, ores, alloys, glass, ceramics, soils, sludge, plant parts, cereal grains, oil seeds, plastics, waste samples, wool and textiles and many more
Product Advantages
- quick, efficient pulverization and homogenization
- high sample throughput due to short grinding times and two grinding stations
- reproducible results due to digital setting of grinding time and vibrational frequency
- large range of grinding jars
- 9 parameter combinations can be stored
- simple and comfortable operation
- 2-year warranty, CE-conforming

Function Principle  The grinding jars of the MM 200 perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. Also, the movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample. The degree of mixing can be increased even further by using several smaller balls. If several small balls are used (e.g. glass beads) then, for example, biological cells can be disrupted. The large frictional impact effects between the beads ensure effective cell disruption.
