An NMR spectrometer (') has a sample changer (&#x2032;) with at least one cylindrical sample holder () for receiving an elongated NMR sample at a loading position () and for transferring the NMR sample into the measurement volume at a transfer position (). The sample holder is open in an upward direction and the cylinder axis of the cylindrical sample holder is inclined at the loading position by an angle of inclination a of between 30 and 60 degrees with respect to the vertical and it extends vertically at the transfer position. A positioning device is provided, which transfers the NMR sample at or after the transfer position into the measuring position in the measurement volume with a vertically aligned sample axis of the NMR sample. The spectrometer enables a more ergonomically favorable feed of the sample.

A sample exchange device (), in particular, for an NMR spectrometer, comprising a circumferential chain (), sample receptacles () which are disposed on the chain () at equal distances and are connected to each other via webs (), and a measuring or transfer position (), wherein each sample receptacle () can be moved to the measuring or transfer position () by moving the chain (), characterized in that a chain guidance is provided which guides the circumferential chain () along a meandering path. The inventive sample exchange device is particularly economic and does not impair the analysis of the samples.

A device and a method for characterizing and identifying an object, e.g. a container, with a surface visible from outside the object, onto which is disposed an optically readable one-dimensional bar code consisting of bars and spaces, are characterized in that the bar code is disposed in an annular range ( ) of the surface, that the bars and spaces extend in a star-like manner from a center of the annular area ( ) to the outside and that the bar code is read in the circumferential direction of the annular area ( ). This device and method enable automatic detection, recognition and identification of objects, like e.g. sample bottles for spectroscopic analysis in a simple technically undemanding and cheap manner, wherein automatic identification of hollow, in particular hollow cylindrical objects can also be easily realized.
