The separation of fine particles and biological products is a difficult task as the volume of the particles or the density gradient between the particles and the liquid are small. In these cases, centrifuges offer high clarifying potential and throughputs (Bender and Koglin, 1986, Lander et al., 2005, Mosqueira et al., 1981, Smith, 1961).
