Abstract:
A device for operating a microchip with a microfluid structure for chemical, physical, and/or biological processing, the microchip including supply elements corresponding with the microfluid structure, comprisinga supply unit for providing a potential for moving substances corresponding to the microfluid structure, the supply unit having supply lines for enabling the potential to be coupled to the microchip, the supply lines being arranged to interact with the supply elements which correspond to the microfluid structure, an interface element, and a holder for carrying the interface element, the interface element including a structure for connecting the supply lines with at least one of the supply elements that correspond to the microfluid structure, the interface element and the holder having structures for enabling the interface element to be releasably connectable to the holder so that the interface element can be selectively secured to and removed from the holder, the interface element having exterior surfaces resistant to the substances processed by the microchip and further including a magnet/Hall sensor pair, the second assembly including elements mounted on the module, and an output device responsive to a Hall sensor of the magnet/Hall sensor pair.
