The present invention relates to cells () for a centrifugal partition chromatography column, consisting of stacked discs and comprising a network of three-dimensional cells interconnected in series and communicating with liquid phase circulation channels, said cells being distributed over the periphery of at least one disc driven into rotation about a main axis (); the cells have a geometric shape of revolution about a substantially radial axis with respect to said disc and they are connected by channels () of substantially circular, elliptical or parallelepipedic section, the main two dimensions of which are smaller than the largest cross-section of the cell. The invention also relates to methods of manufacturing these cells.

The present invention relates to a system for generating the same instantaneous pressure between two tanks filled each with a given medium, the first tank including at least one inlet channel and at least one outlet channel for the given medium, the second tank including at least one outlet channel, and means for opening and for closing said channels. The system according to the invention further includes at least one linking capillary between each tank, intended notably for transmitting instantaneously a pressure variation from the first tank towards the second tank.
