Abstract

The invention relates to a device and a system for blood separation, comprising a tubular container (1) designed to be rotated about its longitudinal axis by axial centrifugal means. The container (1) has, on one hand, an inner chamber (2) for receiving a blood volume to be separated, the inner chamber (2) being formed by an upper chamber part (4) and a lower chamber part (3) which widen conically towards each other, and, on the other hand, an outer chamber (6) arranged concentrically to the inner chamber (2) and adapted to hold the whole blood cell fraction of the blood volume. The outer chamber (6) is connected to the inner chamber (2) through a narrow slit-shaped space (5) which extends radially from the upper part of the outer chamber (6) to the transition between the two cone-shaped parts (3, 4) of the inner chamber (2) along at least substantially the whole periphery of the chamber. Furthermore, the inner chamber (2) has an opening (7, 8) at one or both of the outer ends of the upper and lower chamber parts (3, 4), which opening or openings (7, 8) are closed by closure means (9, 10) for retaining blood in the container (1) but which closure means may be affected to permit introduction and withdrawal, respectively, of blood therethrough.
