    • PROBLEM TO BE SOLVED: To provide a shaking vessel of high oxygen-absorbing efficiency for mass cultures which is useful even in a high shearing field if the field is oxygen-absorbing rate determined. SOLUTION: The bottom side of a flask is changed to be a spherical bottom from a flat bottom, so that the area of a liquid membrane generated in the vessel become larger and the liquid free surface area for absorbing oxygen is increased. Then, a feeding amount of liquid can be increased than a conventional round-bottle flask by making the upper part of the flask a cylindrical type, so that a mass treatment is possible. A liquid mixing is suitably maintained without retarding a revolution flow generated in the vessel by making a baffle shape a semi-cylindrical type. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:为大规模培养提供高氧吸收效率的摇动容器,如果确定了氧吸收速率,即使在高剪切场中也是有用的。 解决方案:将烧瓶的底侧从平坦的底部改变为球形底部,使得在容器中产生的液膜的面积变大,并且用于吸收氧气的无液体表面积增加。 然后,通过使烧瓶的上部成为圆筒型,可以比现有的圆瓶中的液体的供给量增加,从而可以进行质量处理。 适当地保持液体混合,而不会通过制成半圆柱形的挡板形状而延迟容器中产生的旋转流。 版权所有(C)2007,JPO&INPIT
