ABSTRACT:
A supply element for a microfluid microchip that can be used for chemical analysis has supply lines or reservoirs that serve to supply the microchip with substances or reagents. Both ends of the supply lines are sealed to prevent the substances from leaving the supply element or contaminating the contained substances before an experiment. In addition, supply lines are provided that are designed as contact pins to transfer electrical voltage from the supply device to the microchip and serve to offer the required electrical potential for moving the substances corresponding to the microfluid structure of the microchip. The supply element permits the microchip to be easily supplied according to the cited requirements with the required substances for a respective experiment and, in particular, has the advantage that only the supply element itself directly contacts the microchip and can be soiled or worn. The supply element can also be advantageously exchanged with a new element between individual experiments to advantageously reduce to a minimum the danger of contamination by substances on the microchip.
