ABSTRACT:
A device for separating at least part of the liquid component of a blood sample and methods thereof are disclosed. Generally, the device includes a container body for receiving the blood sample, a layer of retaining porous material, a layer of separating permeable material. The retaining porous material retains non-liquid components of the blood sample after the non-liquid components have been subjected to centrifugal force which forces them through the separating permeable material into the retaining porous material.
