With the new Mixer Mill MM 400 RETSCH has developed an extremely versatile bench-top unit which combines easy and safe handling with maximum flexibility for your sample preparation process. It is used for dry, wet and cryogenic grinding of small sample volumes up to 2 x 20 ml.
The MM 400 covers a huge range of applications: from mixing and pulverizing to cell disruption for DNA/RNA- and protein extraction and mechanochemical processes.
New features include storage of 12 SOPs and 6 program cycles, a maximum grinding time of 99 hours and the possibility to calibrate time and frequency. This is particularly helpful to ensure highest possible reproducibility and consistent results, as required, for example, in the pharmaceutical industry.
The MM 400 is operated with grinding jars that are available in 7 materials and 6 sizes, including transparent PMMA jars for in-situ Raman spectroscopy, and a range of adapters for single-use vials from 0.2 ml to 50 ml.
The scope of typical sample materials is impressive. The MM 400 is employed in areas like agriculture, biology, chemistry, environment, food, geology, metallurgy, ceramics, pharmaceuticals, to name but a few.
