The RETSCH 207150001 Mixer Mill MM 400 is a compact bench-top unit for a wide range of grinding applications. Whether you need to dry, wet or cryogenic grind small sample amounts, this mixer mill can do it all. In a few seconds it mixes and homogenizes powders and suspensions, perfect for various applications.
Not only can it grind and mix different materials but also disrupt biological cells and process biological samples, extract DNA/RNA and proteins. High performance and flexibility make it a unique product in the market, you get the functionality you need for your lab or research.
Accessories like transparent pmma grinding jars and balls need to be ordered separately as they are not included with the mixer mill. But they are available to buy.
If you need a mill with high input you might also want to look into the planetary Ball Mill Emax. This mill introduces a completely new type of grinding, high friction and impact to get extreme fine particles in no time.
The function principle of the Mixer Mill MM 400 is the grinding jars oscillate radially in horizontal position. The inertia of the grinding balls makes them impact with energy on the sample material and pulverize it. The movement of the grinding jars and the balls also ensures intense sample mixing. The degree of mixing can be increased by using smaller balls, especially for disrupting biological cells.
The Mixer Mill MM 400 can be used for various applications like grinding and homogenization of alloys, animal feed, bones, ceramics, cereals, chemicals, electronic scrap, glass, grains, hair, minerals, oil seeds, ores, paper, plant materials, plastics, sewage sludge, soils, straw, tablets, textiles, tissue, tobacco, waste samples, wood, wool and more.
With reproducible and efficient grinding, mixing and homogenization the Mixer Mill MM 400 saves you time and effort in your lab work. Powerful grinding through impact and friction, dry, wet or cryogenic grinding mode. Screw-top grinding jars leak-proof grinding and up to 9 standard operating procedures (SOPs) can be stored.
To increase its functionality the Mixer Mill MM 400 is compatible with a wide range of accessories like different jar and ball sizes, adapter racks for single-use vials and tubes, various grinding tool materials and the CryoKit. It also disrupts up to 240 ml cell suspension for DNA/RNA and protein extraction.

Overview and Features
RETSCH MM 400 Mixer mill is a versatile and powerful lab tool for dry, wet and cryogenic grinding of small sample amounts. With its compact bench-top design the Mixer Mill MM 400 is perfect for mixing and homogenizing powders and suspensions in a few seconds. The mill has 2 grinding stations to prepare up to 20 samples at the same time. High-performance grinding for size reduction at each grinding stations, mixing, homogenization, cell disruption and cryogenic grinding.
Function Principle
The grinding jars of the Mixer Mill MM 400 oscillate radially in horizontal position. The inertia of the grinding balls hits the sample material at the rounded ends of the grinding jars with high energy and pulverizes it. The movement of the grinding jars combined with the movement of the balls mixes the sample. The degree of mixing can be increased by using several smaller balls. If several small balls (e.g. glass beads) are used then, for example, biological cells can be disrupted. The large frictional impact between the beads disrupts the cells.
Sample Material and Grinding Modes
The Mixer Mill MM 400 can process various sample materials like tablets, minerals, bones, tissues, soils and plastics. It can be used for dry grinding, wet grinding and cryogenic grinding. The grinding jars are available in different sizes and materials (stainless steel, tungsten carbide, glass) to accommodate different sample types and grinding modes. The grinding balls are designed for cell disruption and intensive mixing, perfect for biological cell disruption and protein extraction.
