Blood analyzer system

Apparatus for performing chemical tests comprising:

• (a) a centrifuge having a rotor with a plurality of cuvette mounting stations thereon;
• (b) at least one reagent containing prepackaged cuvette having a test chamber portion therein and test information coding thereon and mounted on the rotor of said centrifuge at one of said stations;
• said test information coding corresponding to the test to be run in said cuvette;
• (c) a spectrophotometer mounted on said centrifuge and adapted to read the test chamber portion of said cuvette;
• (d) means for reading the test information coding on said cuvette, said code reading means being mounted on said centrifuge;
• (e) and means for receiving a signal from said code reading means and a signal from said spectrophotometer and for displaying the test result appropriate for said test information coding.

Apparatus for performing chemical tests comprising:

• (a) a centrifuge having a rotor with a plurality of cuvette mounting stations thereon;
• (b) a plurality of reagent containing prepackaged cuvettes each having a test chamber portion therein and test information coding thereon and mounted on the rotor of said centrifuge each at a different one of said stations;
• said test information coding on each of said cuvettes corresponding to the test to be run for said cuvette;
• (c) a spectrophotometer mounted on said centrifuge and positioned to read the test chamber portion of each of said cuvettes;
• (d) means for reading the test information coding on each cuvette as it passes a given location on the centrifuge and for simultaneously reading the station at which the cuvette is mounted, said code reading means being mounted on said centrifuge;
• (e) and means for receiving a signal from said code reading means and a signal from said spectrophotometer and for displaying the test result for each station appropriate for said test information coding.

Chemical test apparatus comprising:

• two pump sections of different dilution capability each having an aspirator dispenser hose;
• said apparatus having a receptacle therein which is shaped to permit insertion of a cuvette only when the cuvette is in a given orientation relative to said receptacle;
• a pair of switches mounted on said apparatus, one associated with one of said pump sections and the other associated with the other of said pump sections;
• each of said switches being positioned to be actuated by tab on the cuvette with the tab being oriented in accordance with the desired dilution of the liquid substance to be inserted into the cuvette.
