Biotechnology combines microbiology and biochemistry. For research and development purposes, it is necessary to get inside the cells. So-called cell disruption is required to separate homogenates from cell walls. When grinding with a DISPERMAT® agitator ball mill, gentle processing is essential. With the infinitely adjustable DISPERMAT® basket and bead mills, the desired cell disruption is achieved. The size of grinding beads and the peripheral velocity of the milling rotor are the critical parameters for achieving the desired quality.
