Abstract
A mass and/or heat exchanger includes at least one bundle of capillaries, the ends of which are embedded in a casting composition, and a housing in which the capillaries with the casting composition are arranged in such a way that the casting composition represents a liquid-tight isolation between the lumens of the capillaries and the space outside the capillaries. An elastic element which compensates for differences in changes of length of the at least one bundle of capillaries and the housing, is provided between the casting composition and the housing.
