Ø  Main Application:

u  RETSCH MM301 type of ball mill is suitable for grinding, mix small amount of sample processing, it not only applicable to dry samples and also apply to wet samples; MM301 also can be used in the crushing of biological cells and the separation of DNA and RNA.

u  In the normal temperature and freezing conditions of rigid, hardness, toughness, brittleness and fiber material grinding broken. For example:

l  Pretreatment of the sample of plants, animals, pollen, spores, cell disruption under normal temperature and freezing conditions and extract the gene；

l  Grinding and crushing heat sensitivity materials, such as chemicals, plastics, polymer materials, resin and so on under normal temperature and freezing conditions；

l  Fast and efficient grinding ceramics, glass, mineral and soil under the condition of normal temperature. It is widely used in sample preparation of large testing instruments, such as ICP, X-ray diffraction；

l  Pretreatment of hair, bones, teeth and other forensic samples before the analysis at frozen and room temperature.
