A system for preparing blood samples for analysis is described comprising: a whole blood sample disc having first radial passageways arranged therein in spoked array, a serum sample disc removably secured to the whole blood sample disc and having second radial passageways arranged therein in spoked array, a sample preparation rotor having a center cavity for receiving and removably holding the whole blood and the serum sample discs, means for rotating the sample preparation rotor to separate a plurality of whole blood samples into serum and solids in the separate cavities. The cavities and the serum capillary tubes are of sufficient size such that the serum migrates by capillary action from the separate cavities into the serum sample capillaries after rotation of the apparatus is halted.
