    Abstract: A microfluidic chip interface for providing fluid communication with external fluid sources and external fluid waste containers, and for providing electrical contact with voltage sources and voltage and current measuring devices, is described. The microchip is first placed into electrical communication with at least one electrical source and at least one electronic measurement device, and reversibly secured in place. Chosen fluids are provided into the microchip and directed through the chip using a fluid manifold having dispensing tubes and fluid aspiration tubes, which is brought into the vicinity of the secured microchip. The distance between the fluid manifold and the microchip is chosen such that the injection tubes are located within wells in the microchip connected to microfluidic channels, and the aspiration tubes are located near the surface of the microchip in the vicinity of the wells such that fluid spillage onto the surface of the microchip during fluid transfer is avoided. The fluid manifold is removed from fluid communication with the microchip during electrical measurements.
