Process and apparatus for the bubble-free aeration of liquids, in particular culture media for the propagation of tissue culture

摘要: In a method and device for the bubble-free gassing of liquids, in particular culture media propagation tissue cultures, which gas exchange takes place over an immersed membrane surface, input desorption without mechanical distribution is achieved simple effective, as uniform possible Damage to liquid components A tubular basket (20) formed from hollow threads (24) flexibly suspended medium be gassed moved circular motion self-rotation. The rate controlled by changing pendulum frequency / or radius path alternatively concentration pressure flowing into (20).
