Abstract

The invention relates to a device (1) for sampling, comprising a housing (2) having a housing chamber (8) which has two connection openings (10) for connecting one line portion in each case. The device (1) includes a withdrawal element (13) which is movable in the housing chamber (8). The withdrawal element is formed, at least in portions, in a profile-like manner, and bounds a hollow sampling region (19), extending along a profile longitudinal direction course (16), at the periphery of the sampling region, while leaving an entry opening (21) which extends along an opening longitudinal direction course (20). Guide means are provided by means of which a defined movement pattern of the withdrawal element (13) in the housing chamber (8) is predetermined, via which movement pattern at least one of the two opening cross-sections (32) in a projection view perpendicular thereto may be traversed over the entire area by means of the entry opening (21). The invention proposes that as a result of the movement pattern specified by the guide means, an orientation of the withdrawal element (13) in an observation plane which moves with the withdrawal element relative to a geometric intersection line of the observation plane with a nonmoving geometric reference plane which extends perpendicular to the observation plane and to at least one opening cross-section (32), remains the same when the withdrawal element (13) is moved.
