摘要： The invention relates to a pipetting apparatus for an automatic analysis device, which is particularly stable and allows simple and error-proof replacement of the pipetting apparatus and, therefore, particularly reliable operation of the analysis device. To this end, an essentially frustoconical fastening body is arranged around an axial region of the needle body.

摘要： The invention relates to a hollow needle (1) for a sample pipettor in an automated analysis instrument, which sample pipettor is suitable for withdrawing sample liquid from a sealed sample vessel by virtue of the cover or the cap of the sample vessel being pierced by the hollow needle (1). The hollow needle (1) has a substantially straight cylindrical basic shape with a tip (8) for piercing a cover and enables a removal of sample liquid, comparatively less susceptible to errors, from a sample vessel in an automated analysis instrument. In the region of the tip (8) of the hollow needle (1), a number of faces (22, 26, 28, 30) have been introduced in such a way that the radial force components resulting at the respective faces (22, 26, 28, 30) during an axial movement into an elastic material cancel one another.
