A two-part test cartridge for use in a centrifugal analyzer for measuring the concentration of different electrolytes in blood or blood serum samples has one part which is disposable and which is characterized by a sample entry port, one or more filled calibrant chambers, a waste chamber and passages between various chambers; and a second, mating part which is reusable and which is characterized by an ISE, a power supply and circuitry therefor, and a series of chambers and passages adapted for communication with the series of chambers and passages in the disposable part.

Two-part test cartridge for centrifuge

A sample processor card for use with a centrifuge in which the direction of centrifugal force can be altered at will, wherein the card includes a supply of chemical reagent and inlet means for supplying a chemical sample to the card. The sample is advanced under centrifugal force through capillary means to sample measuring means, and the measured sample is then mixed with reagent to permit a chemical test to be carried out on the reagent, all under centrifugal force.

An improved centrifuge, including a main wheel for rotating objects to be subjected to centrifugal force about a main axis of rotation, is disclosed. Such objects are simultaneously rotated about a second axis of rotation from a first to a second position, and the centrifuge is improved by the inclusion therein of multiple reversing induction motors including a stationary stator and multiple induction rotors attached to the main wheel that eliminate electrical slip rings or mechanical linkages as controls for effecting the rotation of the objects from the first to the second position.
