Retsch Mixer Mill MM 400

The Retsch mixer mill MM 400 is a compact versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of small amounts of sample.

It can mix and homogenize powders and suspensions in only a few seconds. It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA and protein extraction. With its high performance and great flexibility the mixer mill MM 400 is a great tool for your laboratory.
