57 Zusammenfassung AB [DE] Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur blasenfreien Begasung von Flssigkeiten, insbesondere in der Biotechnologie und speziell von Zellkulturen.
[EN] The procedure for gassing of liquid for cell cultures, comprises exchanging of gas over immersed membrane surfaces like hoses, cylinders or modules, and controlling the gassing rate change of the gas concentration and/or pressure of the gas or gas mixture or gas component flowing into/out of the area within the membrane surface. The membrane surface represents any rotatingly oscillating movement in the liquid. The gassing rate, transfer efficiency, mixing time and/or shear stress are controlled by change of the movement like amplitude and the equivalent number of revolutions. The procedure for gassing of liquid for cell cultures, comprises exchanging of gas over immersed membrane surfaces like hoses, cylinders or modules, and controlling the gassing rate change of the gas concentration and/or pressure of the gas or gas mixture or gas component flowing into/out of the area within the membrane surface. The membrane surface represents any rotatingly oscillating movement in the liquid. The gassing rate, transfer efficiency, mixing time and/or shear stress are controlled by change of the movement like amplitude, the equivalent number of revolutions, acceleration of the membrane surface, the delay of the membrane surface, the interruption of the movement or discontinuity. The course of motion is not restricted to recurring samples. The material transfer is increased by mounting of immovable current interfering elements. The disturb of the current forms by the rotatingly oscillating movement of the membrane surfaces. The supply of the membrane surface is undertaken with the help of flexible hoses or turning seals for the supply and discharge of gas. The membrane surface is used for the production of micro-bubbles or gas bubbles in the liquid. Rotor arms rotate in one of the rotation directions curved around the drive shaft. An independent claim is included for a device for gassing of liquid for cell cultures.
