Retsch Mixer Mill MM 400, 100–240 V, 50/60 Hz, with quick release clamp (please order grinding jars and balls separately)

A ball mill for powerful size reduction and homogenization

RETSCH ball mills are available as mixer mills as well as planetary ball mills.

Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. They are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery.

RETSCH’s innovative Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding down to the nano range. They are used for the most demanding tasks, from routine sample processing to colloidal grinding and advanced materials development.

The High Energy Ball Mill Emax is an entirely new type of mill for high energy input. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

Function Principle

 

The grinding jars of the MM 400 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.
