Abstract: The invention relates to a flow element for transferring fluids comprising a capillary cartridge (1) having an integrated capillary line (3). The capillary cartridge according to the invention (1) has a ring-shaped channel (8) and securing grooves (6, 6?), wherein the flow element is characterized in that the capillary line (3) is arranged in the ring-shaped channel (8). The ends of the capillary lines (3) are connected to connection elements (9) in which securing grooves (6, 6?) are secured in a positive locking manner. The flow elements according to the invention contribute toward improved manageability and effectiveness of components. In a preferred embodiment, the flow elements are used as a distribution system in the form of a plurality of capillary cartridges (1-1, 1-2, . . . ). Such distribution systems are of technical importance in the field of catalyst testing apparatuses with reactors arranged in parallel.
