    • A nuclear magnetic resonance (NMR) spectrometer probe head having one or more drive units, one or more transmission units and one or more drive shafts which are coupled to adjustment rods and a means for directly mounting and fastening the drive unit, transmission unit, and drive shaft to the lower portion of the probe head during operation of the NMR spectrometer, which increases user comfort and freedom of motion below the magnet. The probe head also having an actuator for remote control adjustment of electrical and/or mechanical units, e.g. trimmer capacitors, variable resistors, and adjustable inductors within the probe head. The probe head is characterized in that the amount of space needed for the actuator is minimized, access to the region below the magnet is optimized, and installation of the actuator is simplified because the actuator is an integral part of the NMR-probe head within an NMR-spectrometer.

    • In a temperature-control device for samples, in particular for NMR spectroscopy, comprising a vessel (20) provided with an opening (19) for receiving a measuring sample (1), an inlet opening (10) for introduction of the fluid, an outlet opening (15) for the outflow of the fluid and a flow channel (18) through which at least a partial flow of the fluid is guided past the sample (1), as direct fluid flow, from the bottom to the top, there is provided at least one by-pass channel (17) which is arranged in such a way that an additional partial fluid flow can be guided past the upper area of the said sample (1) in the form of a by-pass fluid flow (7). This enables also the upper area of the sample (1) to be temperature-controlled in an efficient way so as to minimize the temperature gradient in the sample (1). The temperature-control device may comprise, in the upper area of the sample (1), a heat-exchanger system (14) which concentrates the direct fluid flow ( 8), after it has been combined with the by-pass fluid flow (8), around the sample (1). One achieves in this manner efficient temperature control of the upper section of the sample by the fluid flow, without any disturbing thermal obstacles.
