Abstract: A sample-taking unit having a sampling unit and a hold-down device which is movable relative thereto in a parallel manner, said sample-taking unit including a self-holding mechanism which, as a result of a self-locking effect, automatically fixes the hold-down device in a lowered fixing position against an upward movement until the self-locking effect is removed again as a result of the self-holding mechanism being acted upon with a detaching force, preferably as a result of contact between the sampling unit and a clamping element of the self-holding mechanism.

Abstract: The present invention relates to a needle (1), wherein the needle (1) comprises a channel (12) extending through the needle (1), wherein the needle (1) comprises a needle tip (11), wherein the channel (12) comprises an opening at the needle tip (11), wherein the needle (1) defines an axial direction (x), wherein the axial direction (x) defines a distal direction and a proximal direction, wherein the needle tip (11) is a distal portion of the needle (1), and wherein the needle tip (11) comprises a first surface section (112) and a second surface section (111), wherein the first surface section (112) is arranged at a first angle (α) with respect to the axial direction (x) and the second surface section (111) is arranged at a second angle (β) with respect to the axial direction (x), wherein the first angle is different from the second angle. The present invention also relates to a corresponding apparatus, system and use.
