ABSTRACT:
In a method of separating different density fluid components, a fluid sample is placed in a first flexible container. The container and its contents are then spun at high speed while controlling the shape of the container so that its side walls spread apart and its bottom flattens to give the container and its contents a relatively small aspect ratio whereby different density components of the fluid contents travel minimum distances while separating in the container to achieve a density distribution in the container, with the densest components of the fluid distal to the spin axis being distributed over a relatively large area surface constituted by the container bottom. The method is particularly applicable to separating different components of human blood. Various apparatus for practicing the method are also disclosed.
