Abstract
In the method for quantitative evaluation of agglutination reactions between a reagent and a biological fluid to be examined, the reagent and the biological fluid are intimately mixed by a horizontal circular movement. The agglutinates formed in the mixture while the circular movement is maintained are optically imaged thereafter on a ground glass plate, and the image is evaluated using an electronic evaluation device.
Claims7
A quantitative evaluation apparatus comprising:
- a condenser;
- means for holding a transparent specimen slide, the holding means including a movable plate having a cutout defining a measuring field;
- an objective;
- a transparent plate;
- an optoelectric evaluation device;
- a frame;
- a support connected to the movable plate via a connecting element, the support including a support plate that is connected to the frame, the movable plate being supported on the support plate via pins guided through thrust bearings;
- a light source constructed and positioned so as to emanate a beam of light along a path sequentially through the condenser, the measuring field, the objective, the transparent plate and to the optoelectric evaluation device;
- and
- means for orbitally agitating in a single plane the holding means while the measuring field is in the path, the agitating means including a drive motor having a shaft, and a coupling connecting the drive motor to the movable plate, the coupling being arranged offset from and parallel to the motor shaft.
