    摘要: An inverted microscope is adapted so that a specimen thereon e.g. cells can be irradiated by a laser beam. The laser beam is guided from a laser source by a series of adjustably movable reflectors which introduce it into the microscope optical pathway at a parallel-beam region thereof, and through the objective lens of the microscope. A point to be irradiated can be selected by moving the reflectors which may be galvanometrically-movable. The laser beam can be focused together with the microscope image. The movable reflectors are kept within 200 mm behind the objective lens principal plane (PP) to ensure that the laser can be applied all over the microscope viewing field.

    摘要: The present invention achieves a smaller difference between a dissolved oxygen concentration in an upper part of a culture tank and a dissolved oxygen concentration in a lower part of the culture tank. The present invention comprises: a culture tank; a sparger means arranged in a lower part of the culture tank; and multiple impellers being arranged in multiple stages in a vertical direction of the culture tank and having a larger mass transfer capacity coefficient KLa per unit number of revolutions in an upper stage than in a lower stage.
