An analytical cartridge (10) adapted for use in analyzing fluids which contain liquid and solid components. The cartridge includes a plumbing system composed of various wells (38, 48, 50, 55) or chambers which are interconnected by passageways (60, 62, 66, 56, 68). After introduction into the cartridge, liquid samples are separated and transported to a test well utilizing a sequential application of centrifugal force followed by pressurization of the system. The cartridge may be used to measure the concentration of a wide variety of chemical constituents in bodily fluids and is useful in measuring other properties of these fluids which contain liquid and solid components.
