Abstract
Temperature control system for an NMR sample tube (22) using a temperature control device (20) with an interior (21) delimiting a cylindrical wall (39) in the radially outward direction and a plurality of flow channels for temperature-controlling fluid running radially around the interior, of which the radially outermost flow channel (28) is delimited to the outside by a wall (29), and the innermost flow channel (31) by a wall (30) and connected to one another by a first fluid passage (34). The innermost flow channel has a second fluid passage (36) to the interior and the outermost flow channel has a fluid inlet (32). During operation, the wall delimiting the interior in the radially outward direction is temperature-controlled by the fluid so that: abs (TU−TW)≤abs (TU−TFD), where TW is the wall temperature, TFD is the fluid temperature at the first fluid passage and TU is the ambient temperature.
