Abstract
An electrode alignment apparatus may be used with a microfluidic device for accurate and repeatable alignment of electrode pins with reservoirs on the microfluidic device. The apparatus includes a base unit and an electrode block assembly that are moveable with respect to each other from an open position to a closed position. The electrode block assembly includes an interface array that is coupled to an interface array platform such that the interface array is moveable with respect to the interface array platform in three dimensions.
