An osmotic pump for supplying a fluid medium to a reaction chamber defining a first chamber, for example, for supplying a fluid nutrient to a cell culture located in the reaction chamber, is connected to the reaction chamber by a plurality of channels forming a channel system. The osmotic pump provides a continual supply of fluid medium even under zero gravity conditions. The removal and return of expended reaction medium takes place by means of a channel into a second chamber. This second chamber encloses an operating medium for the osmotic pump such that the chambers form a closed system with the corresponding channels.
