A transport device for transporting an NMR sample to a probe head (), having a shuttle () and a locking apparatus () for the rotor (), which, when attaching the shuttle to the probe head, releases the rotor, and having a detecting apparatus for detecting the rotor in the shuttle. The probe head has a positioning apparatus (), which holds the probe head in a defined measuring position relative to the shuttle. The detecting apparatus includes a sensor line, which transmits a signal dependent on the position of the probe head to the shuttle's end. A first portion () of the sensor line is mounted inside the shuttle and extends from the rotor in a transport state to the end of the shuttle. A second portion () of the sensor line is mounted inside the probe head and, in the measuring position, is directly adjacent to the first portion.

A temperature-controlled NMR probe has a lower insert portion formed of multiple parts including two disc-shaped sub-elements that are not mechanically rigidly interconnected, lie flat against one another in the mounted state and are perpendicular to the z axis. The first sub-element (), in terms of material and geometric structure, fulfils the function of electrically insulating the RF and HV lines fed through the lower insert portion, has an electrical conductivity sigma&#x3c;10S/m, mechanically and retains components of the NMR probe constructed on the lower insert portion. The second sub-element () retains the first sub-element on a main frame () of the NMR probe, and is made of a ductile plastics material or metal having a mechanical breaking strength &#x3c3;&#x3e;100 N/mmand a melting temperature T&#x3e;250&#xb0; C. This achieves high breaking strength and resistance to thermal stress while simultaneously attaining required RF and HV properties.

A transport device for conveying an object to be transported () between an input point (A) and a supply point (Z), where the object to be transported () can be supplied to an RT tube () of a cryostat (), wherein the input point (A) is both horizontally and also vertically spaced apart from the supply point (Z), wherein a transport tube () is provided for pneumatically conveying the object to be transported within the transport tube () from a first transfer point (B) to a second transfer point (C), is characterized in that the transport tube () is vertically arranged, a first transport container (TB) and a second transport container (TB) are provided for receiving the object to be transported (), a first transfer device is disposed between the input point (A) and the first transfer point (B), and a second transfer device is provided between the second transfer point (C) and the supply point (Z).
