Patent ID: 7811523

Claim:
A microfluidic analytical apparatus comprising: a microfluidic card having, (a) first and second opposed major surfaces, (b) a plurality of microchannels formed between the major surfaces, each microchannel having ports extending to the first major surface of the microfluidic card, thereby forming an array of ports, a circuit card in moveable proximity to the microfluidic card having, (i) first and second opposed major surfaces, (ii) an array of conductive pins projecting from said second surface and disposed adjacent to and projecting toward the first major surface of said microfluidic card in a removably receivable relation with selected ports thereof, said array of pins corresponding to a select array of ports and said pins being arranged in groups, (iii) conductive pads disposed on said first surface of said circuit card, each pad corresponding to and electronically connected to a group of pins, and conductive fingers in electrical communication with a power source and making electrical contact with said pads, said fingers movable horizontally along the first surface of the circuit card, thereby aligning with said pads.
