Abstract

The invention relates to a coupling system that can particularly be applied for interfacing a consumable component with a sample chamber to a laboratory instrument for processing a sample fluid. The coupling system comprises a female interface module (10) integrated into the consumable component that has an elastic sealing component (12) with a preformed channel (12a). Moreover, it comprises a male interface module (20) integrated into the instrument and comprising a hollow needle (23) fixed in a first section (22a) of a bush (22), wherein the flexible free end of said needle (23) is partially surrounded by a second section (22b) of the bush that limits the lateral movement of the needle. The diameter of the channel in the sealing component (12) is preferably smaller than the diameter (d) of the needle (23), thus providing an airtight connection and a self-cleaning effect.
