A device for separating components, such as fibrin I from blood, by way of centrifugation about a central axis of rotation comprises a first annular chamber defined by an outer cylindrical wall and an inner cylindrical wall, both walls being concentrically accommodated about the axis of rotation, and by a top wall and a bottom wall, where the top wall or the bottom wall is formed by a piston body displaceable within the first chamber. The device comprises furthermore a second chamber communicating with said first chamber through a first conduit and being defined by an outer cylindrical wall concentrically accommodated about the axis of rotation, said bottom wall of the first chamber, and another bottom wall. The second chamber is adapted to be placed below the first chamber during the centrifugation. The device comprises also blood feeding means for feeding blood to the first chamber and composition feeding means for feeding composition promoting the separation as well as receiving means for the connection of at least one liquid-receiving container, where the receiving means communicate with the second chamber through a second conduit. A capsule is accommodated in the second chamber and comprises a plurality of compartments for receiving respective compositions promoting the separation. The capsule comprises closing means said compartments and while influenced by the piston being adapted in sequence to open for the release of the contents of the compartments. |
