摘要
Abstract A new device for countercurrent distribution using an aqueous polymer two-phase system was developed. The device consists of a rotating column separated into many loculi in which steel balls are placed as stirrers, and a motor is used to rotate the column at two selected speeds alternately. At the lower speed of rotation with little centrifugal force, the steel balls roll down along the surface of column wall and promote effective mixing, while at the higher speed of rotation the centrifugal force keeps the balls still and accomplishes phase separation. The distribution behavior of cells or cell particles by the device is demonstrated with red blood cells from rat.
