摘要: An apparatus is provided for centrifuging and further automatically handling a container (110) separating component, such as fibrin monomer, from blood. The comprises cylindrical member (27) piston displaceable in said member, comprising tubular rod (8) extending through top wall (73). divides the into first chamber (70) positioned above between (73), second below piston. (73) of an extension (90) defining circumferential slit surrounding outer side (8), whereby one end communicates axial direction with chamber. In addition, plurality channels according to invention supporting turntable (101) means releasably retaining (27), being connected activating (105) rotating about central axis thereof, well rotatably journalled mechanism (113, 118) adapted activate (55) by (115). optical blood cell detector (130) which emit light beam obliquely towards (91), detecting observing intensity reflected beam. control (131) controlling response measurements means.
