Abstract

See full text

The automatic chemical analyzer includes a turntable adapted to hold a plurality of disposable cuvettes. An optical system adjacent to the turntable can perform analytical absorbance or fluorescence tests on the contents of each cuvette as they are rotated on the turntable. A sample/reagent tray is rotatably mounted about an axis parallel to the turntable axis. A common probe arm pivoted about a third parallel axis mounts a pipette that can be moved along an arcuate path intersecting a cuvette access station on the turntable and at least one container access station on the sample/reagent tray for transferring liquids as required by specific test procedures. A sample tube entry port is provided to support individual draw tubes that are manually delivered to the analyzer at a sample access station and to facilitate removal of samples by the pipette without exposing operating personnel to accidental contact with liquid materials in the draw tube.
