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.

Device for the photometric examination of samples

The present invention relates to the field of the use of automated measurement systems in analysis and in in-vitro diagnosis. In particular, the apparatus described enables automatic quality control and validation of characteristic process engineering parameters, in particular characteristic optical parameters, during the measurement of scattered light signals.

Nephelometric detection unit with optical in-process control

A method and apparatus for spectrophotometric and/or nephelometric analyses. The apparatus can be used in in-vitro diagnosis.

Spectrophotometric and nephelometric detection unit

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.

Apparatus (cuvette) for taking up and storing liquids and for carrying out optical measurements

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.

Mass-sensitive biosensors

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.

Biosensor

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.
