System for thermocycling of fluids in cartridges comprising a thermocycling unit in thermal contact with a first substantially planar and heat conducting wall of a cartridge, a light source for transmitting light into the interior of said cartridge through a second light transparent wall of said cartridge which is arranged substantially perpendicular to said first wall, a light detector for detecting light emerging from the interior of the cartridge through said second wall and a fluid providing unit coupled to an inlet of the cartridge for providing the cartridge with fluid and an outlet of the cartridge to drain gas when the cartridge is filled with fluid. The invention further concerns a cartridge for conducting the thermal cycling of fluids.

A photoelectric module ( ) comprises an electrically non-conducting support ( ) and a photoelectric element including an array of spatially distributed photoelectric members applied to a surface of the support ( ). High simplicity and efficiency is obtained by the double function of module ( ) for light transmission or reflection, and spatially averaged light measurement. In a preferred application of module ( ) a light source ( , LED) is energized by a driving circuit ( ) controlled by an electronic circuit ( ). The input of this circuit ( ) is connected to the photoelectric module ( ), the power delivered to the light source ( ) and the intensity of the light beam emitted by the light source being regulated preferably to a constant value by the feedback loop consisting of module ( ), electronic circuit ( ) and driving circuit ( ).

Method and a device for measuring the spatially averaged intensity of a light beam and a method and a device for regulating a light source

The present invention refers to an apparatus for transporting components within an automatic analyzer system. In order to provide a simple and low cost apparatus for transporting components within an automatic analyzer system, the apparatus comprises a component carrier suitable for holding a plurality of components; transport means for transporting the component carrier from a first position in a first apparatus which has a first housing and forms part of the analyzer system to at least a second position in a second apparatus which has a second housing and also forms part of the analyzer system; and a third housing containing the transport means and connected with the first housing of the first apparatus and aligned with the second housing of the second apparatus.
