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.

System for thermocycling of fluids in cartridges

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 ( ).
