Abstract: A device for culturing cells in a shaking operation with passive gas exchange, which includes at least one gas exchange opening, characterized in that the opening surface of the gas exchange opening is not oriented parallel with the movement vector of the shaking movement at at least one point in time of the shaking movement. Owing to the shaking movement and the ambient gas phase flowing around the outside of the device and the headspace gas phase flowing around the inside of the device, which flowing is associated with the shaking, the arrangement leads to the formation of a pressure gradient between the headspace gas phase and the ambient gas phase, which pressure gradient changes depending on the shaking movement and advantageously influences the gas exchange between the headspace gas phase and the ambient gas phase and the gas blending within the headspace.
