A blood component separating device comprises a centrifuge bowl adapted for rotation about its axis in a centrifuge. The bowl defines an outer arcuate wall plus an inner circumferential wall, spaced from the outer wall, to define a arcuate slot adapted for receiving blood components. Access tubing is adapted for communication with the slot. Preferably, an elongated, flexible, collapsible inner liner is provided in the slot. Individual access tubing also may communicate with an elongated container interior between the ends of the elongated, collapsible container. Furthermore, a portion of the slot may define the shape of an outwardly extending spiral, to provide an increasing gravitational field upon fluids therein as the fluid moves along the slot.

A blood component centrifuge assembly comprising a rotor, said rotor having a rigid bowl for rotation about a centrifuge axis; means providing a multi-portion blood receiving channel in said rotor, said bowl containing separable outer and inner walls defining said blood receiving channel, one portion of said channel being arcuate and having a constant radius extending from the true center of said rotor, another portion of said channel being spiral-like with portions disposed at progressively different distances from the true center of said rotor; and fluid connection means at separated locations of said channel for introducing blood and extracting blood components from said channel.
