    • PROBLEM TO BE SOLVED: To provide a robust fluidic connection system of a zero dead volume.SOLUTION: The 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 which includes a front end face for abutting against the end seal face of the port in a sealing state. On the capillary tube, a flange may be affixed at a prescribed distance from the front end face of the capillary tube. The fluidic connection system may further comprise a fitting nut which 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.
    • 要解决的问题:提供一个零死体积的鲁棒流体连接系统。解决方案:流体连接系统可以包括一个端口,该端口包括具有端部密封面和螺纹壁的毛细管插座。 流体连接系统还可以包括毛细管,其包括在密封状态下抵靠端口的端部密封面的前端面。 在毛细管上,法兰可以与毛细管的前端面规定的距离固定。 流体连接系统还可以包括配合螺母,其包括允许毛细管通过的轴向孔和对应于端口的螺纹壁的匹配的螺纹壁。 接头螺母可以与法兰后面的毛细管可滑动地连接。 法兰固定的距离可以是预定的,使得当凸缘由配合螺母向前推动时,毛细管的前端面直接抵靠端口的端部密封面。
