摘要

The centerer has an inner tube including a cylinder (1) and a feed through (2) that is provided in a mass. An insertion slot (3) is provided for laterally clipping the centerer on a sample holder i.e. cotton wool wad. An outer end of the slot is provided with a facet. A cylindrical molded part is fitted on a sample holder or directly integrated in the holder. A distance piece (4) includes circularly arranged cuboids with which all edges are folded. The cuboids form a springy construction, which is adapted to geometry of a laboratory container, by an inclination of the distance piece.
