Abstract
The invention concerns a centrifuge intended for use in mainpulating liquid batches on an analytical scale. The centrifuge consists of a body (2) rotatable about its axis (1) provided with input and output conduits (8,9,11) and presenting the essential feature that therein are contained two parallel, circular arc-shaped volumes (3,4) located at different distances from the axis (1) of the body (2) constituting the center of curvature, and communicating with each other through a narrow gap (7) so that when the body is rotating, the heavier components of the liquid accumulate in the volume (4) further away from the axis, and the lighter components accumulate in the volume (3) closer to the axis, whereafter one of these two volumes can be emptied through a conduit (12), while the surface tension acting in the gap between the volumes keeps the liquid in the other volume in its place. The centrifuge of this invention is particularly appropriate for separating blood plasma from the red and white cells in the blood.
