Preparative and analytical centrifuge
WebThe principle of the centrifugation technique is to separate the particles suspended in liquid media under the influence of a centrifugal field. These are placed either in tubes or bottles in a rotor in the centrifuge. Particles differing in sizes, shape and density are separated as their sedimentation rate is different. WebCountercurrent chromatography (CCC) is a liquid-liquid separation technique particularly adapted to preparative separations. In spite of the broad range of applications possible, CCC is mainly applied to the purification of natural products from complex mixtures, field in which some of the characteristics of CCC make it advantageous over other more common …
