US Patent:

53148258, May 24, 1994

Filed:

Jul 16, 1992

Appl. No.:

7/916466

Inventors:

Bruce Weyrauch - Newman Lake WA
Norman Kelln - Spokane WA
Thomas Tiffany - Spokane WA
Robin Olson - Veradale WA

Assignee:

Schiapparelli Biosystems, Inc. - Fairfield NJ

International Classification:

G01N 3500

US Classification:

436 43

Abstract:

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.

G01N 110

US Classification:

422102

Abstract:

A disposable cuvette is molded of rigid transparent plastic resin that is impervious to liquids to be handled within it. The cuvette has a rectangular cross section. Identical side walls extend between upper and lower ends of each cuvette, the upper end being open for reception of liquids and the lower end being closed. Recessed optical surface areas at the lower end are perpendicular to one another for optical testing of the cuvette contents. An elongated cartridge holds a stack of abutting cuvettes to facilitate their handling.
