Mixer Mill MM 500 NANO

Mixer Mill MM 500 NANO

Retsch | Sample Preparation - Inorganic

The mixer mill MM 500 is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds.

With a maximum frequency of 35 Hz, it generates enough energy to produce particles in the nanometer range.The robust high-performance drive makes the mill suitable for long-term grinding processes up to 99 hours. Hence, the MM 500 isaunique mixer mill in the market to provide a real alternative to grinding in a planetary ball mill – with more comfortable handling and less warming effects.

Product Advantages

    • New jar design allows for optimized usage of jar volume also for wet grinding
    • Final fineness < 100 nm possible thanks to maximized energy input at 35 Hz
    • Less warming effects, thus grinding can usually be done without grinding breaks for cooling down.

  • Result: You get your nano sample within the shortest time

  • Very easy, comfortable clamping and handling of the grinding jars
  • Jars can stay clamped while taking a sub-sample or visual checks of fineness
  • Ergonomic design with touch display for easy parameter setting
  • 12 SOPs & 4 program cycles with up to 99 repeats to facilitate routine applications


  • Equally suited for rapid pulverization
  • Use one large grinding ball in the High Impact mode or several smaller balls in the High Friction mode
  • Use the MM 500 nano for routine sample preparation applications, for nano-grinding or for research applications such as mechanochemistry and mechanical alloying
