Abstract
Apparatus for separating a liquid, such as whole blood, into fractions having different densities includes a separation chamber and a transfer device, such as a continuous piece of flexible tubing, for supplying the liquid to the separation chamber and discharging the liquid fractions therefrom. The separation chamber and the transfer device are conjointly rotated about a first axis which passes through a stationary end of the transfer device, while being simultaneously and conjointly rotated about a second axis which is coincident with a medial longitudinal axis of the rotating end of the transfer device so as to prevent the transfer device from twisting as a result of its rotation about the first axis.
