Abstract: A device for the photometric examination of samples has a sample-holder apparatus for at least two sample vessels, and a measuring apparatus and a moveable apparatus. The sample-holder apparatus is designed to be stationary, and the measuring apparatus is arranged on the moveable apparatus such that it can be displaced by means of the moveable apparatus.

Abstract: A reaction vessel (1) with an enclosing wall (4) and an opening (6) for holding liquids to be analyzed enables particularly flexible automatic processing and, at the same time, high quality measurement results. To this end, the enclosing wall (4) comprises a first section (10), in which at least the external surface has a substantially circularly symmetric design, and a second section (12), which has at least two planar areas (14), which comprise a light-transmissive material, are opposite to one another and arranged in parallel, and wherein the reaction vessel (1) has a means (12, 22, 26) for orienting the reaction vessel (1) in a receiving position.

Abstract: An apparatus which permits simultaneous use as reaction vessel for taking up one or more reaction liquids, for incubating and storing these liquids and for carrying out optical measurements is described. The apparatus performs functions of the reaction vessel and functions of the apparatus for liquid uptake. This makes it possible for analysis to be completely free of carryover while, at the same time, requiring minimal use of consumable materials or rinsing solutions.

Abstract: The present invention relates to a piezoelectric sensor for use in diagnostic and analytic processes, in particular for the immunochemical detection of diagnostically relevant specific binding partners.

Abstract: A biosensor (10) for measuring changes in viscosity, density and/or mass in a fluid to be examined, for example a blood coagulation sensor or immunoassay system. According to the invention, the reagents necessary for the test are contained in a support (13) which is put onto the measurement surface (18) of a piezoelectric element (8). As a blood coagulation sensor, the measurement surface (18) may according to the invention itself have a coagulation activator action or else be coated with coagulation activators.

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.
