Abstract:
An apparatus for centrifuging and controlling the temperature in a container (10) for separating a component, from plasma, wherein said container (10) comprises a cylindrical member (11) having a top wall, bottom wall, inner wall and outer wall and a piston (25) displaceable therein and comprising a tubular piston rod (12), which extends through said top wall, and where said piston (25) divides the cylindrical member (11) into a first chamber positioned above said piston (25) between said piston and said top wall and a second chamber positioned below said piston (25), and where said apparatus comprises a supporting turntable (1) with means for releasably retaining the cylindrical member (11), said supporting turntable being connected to a first activating means (5) for rotating the supporting turntable (1) with the container (10) about the central axis thereof, and where said apparatus further comprises a rotatably journalled piston activating mechanism (13, 15, 16) adapted to activate the piston by means of a second activating means (21), characterised in that a heat-emitting device (26, 27) is provided proximate to said outer wall of the cylindrical member (11).
