A microfluidic analytical apparatus (10) comprising a microfluidic card pairing (12) with a corresponding circuit card (14) and the circuit card pairing (12) with corresponding conductive fingers (16). The microfluidic card (12) has a plurality of channels (32) and ports (54) on a top surface of the card in a desired configuration, the ports (54) in fluid communication with the channels (32). The circuit card (14) has a plurality of conductive pins (60) projecting from a bottom surface of the card and having a configuration that corresponds to the particular configuration of the ports (54) of the microfluidic card (12) that is paired with. The circuit card (14) is received within a holder (20) that provides that provides multiple functions. Conductive pads (18) are disposed on a top surface of the circuit card (14), the pads (18) in electrical communication with the conductive pins (60) and corresponding to a configuration of conductive fingers (16) connected to a power source to provide voltage to the microfluidic card (12) for analytical operations. Additionally, detection difficulties associates with non-uniformities present on the card surface are overcome using a detection system incorporating a compliantly mounted microscopic head.
