ABSTRACT:
An analysis system with which a random number of small to very small liquid specimens can be simultaneously examined side by side without hollow reaction vessels. The specimens do not mix together and do not dry out.
To this end, the plates are provided with a water-repelling coating leaving free a number of circular surfaces. The individual specimens are placed between the coinciding circular surfaces of two superimposed plates. A frame ensures that there can be no reciprocal lateral sliding of the plates and that the latter do not move too close to one another. For mixing of the individual specimens, the plates can be rhythmically moved towards and away from one another within given intervals, e.g. by means of a spring-magnet system.
The analysis system can be used in many immunological examinations, particularly blood group determinations, radioimmunoassays, enzyme-immunoassays, immunofluoroescent assays and in non-immunological, general chemical, biochemical and clinical chemical examinations.
