  • Patent number: 12066410
    Abstract: A fastening arrangement fastens a sample holder to a force measuring device. The fastening arrangement has a sample holder, a counterpart holder on the side of the force measuring device. The counterpart holder has a sample holder receptable. The sample holder has a planar abutment surface and the sample holder receptacle has a flat counterpart abutment surface. The sample holder has a positioning element and a fixing element. The sample holder receptacle has a counterpart positioning element and a counterpart fixing element. The positioning element and the counterpart positioning element uniquely define a relative position between the sample holder and the counterpart holder together with the abutment surface and the counterpart abutment surface. The fixing element and the counterpart fixing element hold the sample holder and the counterpart holder against one another and force the abutment surface and the counterpart abutment surface against one another.
