Patent number: 5151362Abstract: By culturing cells in an apparatus containing a first zone in which a cell suspended medium is present and a second zone in which liquid containing a physiological saline solution and/or nutrient sources is present, the first zone being separated from the second zone by a septum with characteristics, such as pores size or electrostatic charges, which impedes the cells from freely permeating through, while allowing at least one of nutrient sources, cell wastes or the product to move between the first zone and the second zone via the septum to proliferate cells in the first zone, wherein a flow rate via the septum is controlled in such a manner that the cell count moved from the first zone into the second zone via the septum does not exceed the cell count increased by cell growth in the first zone. Thus, cell culture at a high cell density can be achieved in a large scale.Type: GrantFiled: April 5, 1990Date of Patent: September 29, 1992Assignee: Hitachi, Ltd.Inventors: Hideo Kawaguchi, Kouji Takeuchi, Tadashi Ishibashi, Norio Shimizu, Yoji Odawara

Patent number: 5130095Abstract: An automatic chemistry analyzer includes a flow cell mounted so that flow through the cell and tubing connected to the cell is visible from the front of the housing. The electrolytes to the cell are removably plugged into the cell from their rear.
