Drawing and operation of the matrix mill for DNA extraction (adopted from US Patent 6063616). Sample is first added into the well (1) of the assay plate (2). The assay plate is then placed into the matrix mill with upper and lower magnetic core and coil assemblies (3, 4) in proximity. The grinding rod (5) is inserted into the well (1). Once alternating current passes through the upper coil assemblies (3, 4) in the frames (6, 7), the magnetically active grinding rod (5) begins the maceration of the sample material within the well.
