Abstract: The present invention is directed to a fluidic interface for delivering a fluid into a microfluidic device, the interface comprising a chamber comprising a first accepting/delivering fluid opening and a second accepting/delivering fluid opening, each opening being positioned opposite to the other, wherein the diameter of the first accepting/delivering fluid opening is smaller than the internal diameter of the chamber and a tubing system connecting the first accepting/delivering fluid opening to a pressure source capable of generating positive or negative pressure. The interface is characterized in that the second accepting/delivering fluid opening is designed to mechanically limit its insertion into a receptacle of a microfluidic device to ensure a predetermined gap (H) between the second accepting/delivering fluid opening and a lower side of the receptacle of a microfluidic device.
