Abstract
A fluidic connection system may comprise a port which includes a capillary tube receptacle with an end seal face and a threaded wall. The fluidic connection system may also comprise a capillary tube that includes a front end face for sealingly abutting against the end seal face of the port. On the capillary tube, a flange may be affixed at a distance from the front end face of the capillary tube. The fluidic connection system may further comprise a fitting nut that includes an axial hole to allow the capillary tube to pass therethrough and a matching threaded wall corresponding to the threaded wall of the port. The fitting nut may be slidably coupled with the capillary tube behind the flange. The distance at which the flange is affixed may be predetermined such that when the flange is pushed forward by the fitting nut, the front end face of the capillary tube abuts directly against the end seal face of the port.
