Abstract: A method of and apparatus for automatically taking monochromatic light absorbance measurements on a plurality of fluid samples such as serum. The fluid samples to be processed are contained in a vessel having a plurality of cuvettes into each of which is disposed a fluid sample to be analyzed and which vessel is on a processing path and moved by a unique drive belt mechanism capable of providing a plurality of movements to the vessel in different directions and selectively to a first position or station whereat the cuvettes in said vessel are washed and evacuated of any unbound materials and then to a second station whereat a reagent is sequentially and serially added to each of the cuvettes, after which the fluid sample in each cuvette is exposed to a monochromatic light absorbance measuring device straddling the track at said second position and a spectroanalysis is made thereof.

Abstract: Apparatus for processing fluids such as blood or the like for ascertaining physical and/or chemical properties thereof. Samples to be processed are contained in disposable containers and moved to different zones where various functions are performed such as adding reagent, incubating, testing, reading out data and discarding the container. The movement of the containers is afforded by a carriage moving on a guideway and having reciprocating embodiment, the containers each carry indicia means identifying the sample and including a test code prescribing a particular test procedure which is to be followed by the apparatus. In another embodiment it is intended that identification of the patient's sample will be initially made on the container which initially receives the sample and thereafter as portions are dispensed from said container for use in processes this identity will be accomplished by suitable computer means.

Abstract: This invention has particular utility in the field of absorption spectrophotometry or colorimetry, and is particularly applicable, when incorporated in such type of equipment, as a sample detector to enable direct readings to be taken in concentration or absorbance of sample fluids or the like.

Abstract: A pipette device enabling single samples of fluids to be readily analyzed under emergency conditions "STAT," as for example, body fluids, and which device is operable to first draw a predetermined volume of a selected reagent material into its chamber, and thereafter in similar manner draw a desired volume of the sample fluid to be analyzed into said device, said reagent material and fluid thereafter being ejected into a suitable reaction vessel wherein the same are admixed preparatory to being analyzed.
