  • Patent number: 11125720
    Abstract: A capillary electrophoresis apparatus is disclosed that does not discharge and achieves both compactness and performance even with a part configuration having insufficient spatial distance or creeping distance. This capillary electrophoresis apparatus is provided with a resistance heater for heating capillaries, an electrode holder that holds capillary electrodes and is connected to a high-voltage unit, and a conductive member that at least partially comprises metal and has been grounded to a low potential. The electrode holder and conductive member are in contact with heat-dissipating rubber disposed there between that composes a structure comprising an insulation member. As a result of this configuration, discharge risk is reduced through the reduction of the potential of parts near the high-voltage unit and the slow reduction of the high potential of the high-voltage unit.

  • Publication number: 20140065704
    Abstract: The present invention provides a simple and highly reliable cell collection system with high throughput and improved in cell collection efficiency. In the present invention, one or more pores are formed in a cell collection plate. One surface of the plate can be directly introduced in e.g., a petri dish, so as to be in contact with a solution containing cells. In this case, means for obtaining an optical image of collected cells from its rear surface is provided to improve reliability and convenience during a cell collection process. Alternatively, the vicinities of the pores in the cell collection plate are only hydrophilized and the other region is made water repellent to improve the efficiency of cell collection.
