METHOD AND SYSTEM FOR THE METERED ADDITION OF FLUIDS INTO REACTION VESSELS

摘要

Proposed is a metering device (87, 54) for introducing a fluid (31) into a reaction vessel such as, for example, a bioreactor (2). The metering device according to the disclosure comprises a closure element (89) for closing the reaction vessel, at least one drop generator (33) arranged in the closure element, and a feed line (91) serving for feeding the fluid to the at least one drop generator. The drop generator comprises a nozzle (36) for dispensing the fluid into the reaction vessel, and a valve (35). In the closed state, the valve disconnects the nozzle from the feed line. The drop generator is suitable for generating individual drops of the fluid.
