Arranged in the outer tube (14) is an inner tube (42) receiving at least the heater. In this arrangement, the inner tube (42) is manufactured from a material having a higher thermal stability than the outer tube, and the inner tube (42) terminates flush with at least the outlet port of the outer tube (14) or projects beyond the outlet port of the outer tube (14) in the direction of flow (64).
