PURPOSE:To enable efficient and continuous sepn. of white blood cells and blood platelets by forming a flat pipe of a centrifugal sepn. part in which an original liquid is passed into a specific construction and utilizing the moving direction where the direction of flow and the direction of settling by centrifugal force are combined. CONSTITUTION:An original liquid is fed from a feed pipe 3 via a rotary sealing means 2 to the top end of a centrifugal sepn. pipe 1 attached to a revolving shaft 8. The pipe 1 is attached in such a way that a flat pipe traces the circular conical surface with the shaft 8 as its centerline in the form of twisting the pipe 90 deg. at its top end and that the 90 deg. twisted part at the top end is in the radial direction and perpendicular to the shaft 8. Apertures are provided in different positions in a sampling chamber 7 which is provided in the bottom end part of the pipe 1 and is extended in the radial direction of centrifugal rotation. Said apertures are connected to suction pipes 4, 5, 6. The pipes 4, 5, 6 are extended via the means 2 and the respective centrifugally separated components are sucked therein.
