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.


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 is the first 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.
