Tempering device for an NMR sample tube

摘要

The temperature control unit (20) has multiple concentric flow channels (28,31) for temperature controlled fluid, which are designed around a cylindrical internal space (21) for incorporation of the nuclear magnetic resonance-test-test tube (22). The flow channels are running coaxial to inner space and are meshed. One of the flow channels, particularly the outermost flow channel of the temperature control unit or the next inner flow channel of the temperature control unit has a fluid outlet (35) at an axial end. An independent claim is also included for a temperature control method for a nuclear magnetic resonance-test tube.
