Retsch Mixer Mill MM200 for 220-240V 50/60Hz 20.746.0001

The mixer mill MM 200 is a compact versatile benchtop unit, which has been developed specially for dry grinding of small amounts of sample.

It can mix and homogenize powders in only a few seconds. It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA extraction. With its high performance and great flexibility the mixer mill MM 200 is a unique product in the market.

Application Examples: alloys, animal feed, bones, ceramics, cereals, chemical products, coal, coke, drugs, glass, grains, hair, minerals, oil seeds, ores, paper, plant materials, plastics, sewage sludge, soils, straw, tablets, textiles, tissue, tobacco, waste samples, wood, wool, etc.

Product Advantages:

- Reproducible, efficient grinding, mixing and homogenization in seconds;

- Powerful grinding by impact and friction, up to 25 Hz for up to 20 samples per run

9 SOPs can be stored

- Wide range of accessories including various jar and ball sizes, adapter racks, grinding tool materials

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.
