A method, and also a gas supply system without a separate humidifying apparatus, for supplying gas to a plurality of bioreactors, divides a constant gas stream with high distribution accuracy into a plurality of gas substreams having a mandated volume flow, which can be kept constant at the mandated level even when during gas supply there is fluctuation in the opposing pressure in the gas line to the respective bioreactor, and decouples a gas distribution from the opposing pressure by hydrostatic pressure compensation, with the gas distribution at the same time producing an obligatory humidification of the gas stream.

Method for gassing bioreactors and gassing system

A gas supply device for operation in an incubator allowing treatment of a culture within a shaker flask with gas independently of the composition and humidity of the gas atmosphere within the incubator individually supplies each shaker flask of the incubator with gas using a gas supply clamp detachably connected to the closure cap of each flask. The gas supply clamp has at least two elastic clamping jaws and a web connecting the clamping jaws to one another. The clamping jaws exert a clamping force on the side wall of the closure cap. The clamp is held in place by the elastic clamping jaws. Above a sterile filter in the closure cap, an individual gas atmosphere for treatment of the culture in the shaker flask is produced in a recess of the web above a gas passage in the closure cap.
