A transfer device is provided for shuttling an NMR sample container between at least two coaxially arranged NMR magnet systems of an NMR spectrometer comprising a guide tube positioned in a central bore of the magnet systems, a shuttle assembly arranged inside the guide tube for securely holding and shuttling the sample container and a drive system comprising a pulling drive and a winch cord attached to the drive system on one side and to the shuttle assembly on the other side, such that the shuttle assembly can travel inside the guide tube. The transfer device has a pneumatic pressurizing arrangement with an entry for pressurized gas arranged on a gas-tight body above the shuttle assembly that is adapted to maintain the winch cord under tension. The shuttle assembly comprises a piston design being moveable along the common axis of the coaxial magnet systems under the influence of the pressure.

A method for measuring an sample in an NMR spectrometer uses a coupling configuration () comprising a coupling element () and a supply capillary (), wherein the coupling element () has a funnel-shaped section () which clamps an end () of the supply capillary (). An envelope capillary () is provided into which the supply capillary () is inserted, wherein the end () of the supply capillary () projects past an end () of the envelope capillary (), and the end () of the envelope capillary () is also clamped in the funnel-shaped section ().
