A method for separating a volume of a blood into a red blood cell component, a plasma component, and a buffy coat component uses a separation set comprising an annular separation container (1) connected to a red blood cell component container (4) and to a plasma component container (2). The method comprising the steps of: - blocking the fluid communication between the plasma container (2) and the separation container (1); - forming a selectively openable circular seal within the separation container (1 ) so as to separate therein an outer annular chamber (18) and an inner annular chamber (17), the circular seal being designed to open when the separation container (1) is spun at a determined rotation speed; - transferring into the outer annular chamber (18) the volume of blood to be separated; - spinning the separation container (1); - squeezing the separation container (1) when the separation container is spun at the determined rotation speed and the seal consequently opens so as to transfer the plasma component into the inner annular chamber (17); - allowing the fluid communication between the separation chamber (1) and the plasma container (2) so as to transfer the plasma from the separation container (1) into the plasma container (2). <IMAGE> |
