Abstract: An interface is provided for storing microfluidic samples in a nanoliter sample chip. A fluid access structure provides a fluid access region to a selected subset of sample wells from an array of sample wells. A fluid introduction mechanism introduces a sample fluid to the fluid access region so that the sample wells in the selected subset are populated with the sample fluid without the unselected sample wells being populated with the sample fluid.

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.
