An automatic analyzer of a single-line and multi-item type having a circular reaction line along which a number of reaction vessels are transported in the stepwise manner, and a photometering apparatus in which white light is divided into a plurality of light beams having different wavelengths, by means of a diffraction grating, and the light beams are transmitted by means of light guides whose exit ends are arranged along the reaction line with a pitch which is different from that with which the reaction vessels are arranged. While the reaction vessels are moved by one pitch, a plurality of reaction vessels are photometered in time sequential manner.

Automatic analyzer

An apparatus for analyzing blood samples by detecting particle agglutination patterns formed on inclined bottom surfaces of reaction vessels formed in a microplate includes a diluted sample preparing section for delivering given amounts of blood cells and serum contained in a sample tube into diluting vessels mounted on a sample plate secured on a rotating endless belt and for discharging predetermined amount of a diluent into the diluting vessels to form diluted blood cell and serum samples, a diluted sample delivering section for delivering given amounts of the diluted blood cell and serum samples contained in the diluting vessels into an array of reaction vessels of the microplate in a selective manner according to test-items to be analyzed and a reagent delivering section for discharging given reagents into the reaction vessels. The microplate having the diluted blood cell and serum samples delivered therein is fed in a substantially stationary manner along a reaction line arranged in a vertical plane and in this reaction line the particle patterns formed on the reaction vessel bottoms are photoelectrically detected.

Analyzing apparatus and method for immunological agglutination reactions

An apparatus for automatic cataphoresis comprises means for feeding a blood serum bearing film; a cutter for cutting the film to a given length; means for supplying a buffer solution for wetting the film with a buffer solution; a blood serum applicator including a serum application member, a serum dish assembly, an abutment, a rinsing vessel, a drip mechanism and means for carrying the film; a cataphoresis compartment for forming fractionated patterns of the serum applied to the film; dyeing, decolorizing and drying stations for dyeing, decolorizing and drying the serum bearing film as it is delivered from the cataphoresis compartment; and a densitometer including a vessel of a clearing liquid, a light source and a detector for effecting a colorimetric determination of the serum specimen. In this manner, a determination of a blood serum is automatically achieved by the cataphoretic process.

Automatic cataphoresis apparatus

A plurality of spaced blood serum samples are disposed on a serum-bearing film having a leading and trailing edge. The blood serum samples are disposed in an array and each blood serum sample has a leading and a trailing edge. A position-indicating mark is disposed forward of the leading edge of the sample closest to the leading edge of the film by a distance representative of the spacing between adjacent ones of the samples.

Blood serum bearing film with position indicating mark

An apparatus for automatic application of blood serum to a serum bearing film for use in a cataphoretic process includes a serum supply station, a serum application station, a rinsing station and a drip station. The apparatus also comprises a guide along which a serum applicator is sequentially moved through each of these stations, as well as operation controlling microswitches and a cam assembly.

Automatic blood serum applicator apparatus for cataphoretic use

An apparatus for automatic quantitative analysis of specimens of a blood serum by a cataphoretic process comprises a supply of a clearing liquid which is supplied to a film on which a plurality of specimens are disposed at a constant pitch, light source means for projecting light onto the film which has been made clear by the application of the clearing liquid thereto, measuring means including a photoelectric transducer element which receives and determines the light which has transmitted through the film, feed means for intermittently feeding the film so as to locate it at a measuring port which is positioned between the light source means and the photoelectric transducer element, and scan drive means for displacing the light source means and the photoelectric transducer means crosswise of the film to scan a particular one of the specimens which is positioned at the measuring port each time the film comes to a stop. In this manner, the film carrying the specimens is made clear by the clearing liquid, and a quantitative analysis is made by scanning the individual specimens by the photoelectric transducer element in the course of the intermittent feed of the film, all in an automatic manner.
