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.

A disposable microbe-collecting carrier cartridge and a carrier treating apparatus which efficiently convert microbes collected on a carrier into a solution and prevent variations in the amount of retrieval of microbes upon concentration on a filter are provided. A cartridge formed of an upper lid having a plurality of through holes, a container in an inverted-cone shape having both of a liquid storage sink unit having a filter at the bottom and an air suction path, and a support base for setting up a thermoplastic carrier, and a carrier treating apparatus formed of a dispensing nozzle for liquid supply, a liquid supply mechanism, a liquid heating mechanism, and a suction pump for filtration are prepared. Warm water is supplied onto the filter set up on a bottom surface of the inverted-cone-shaped. The contact with the warm water causes the carrier to be solated filtered through the filter.

An apparatus includes a system for guiding chemiluminescence and a system for preventing a variation in dark currents. The apparatus includes a first light shielding BOX having a sample container holder and a shutter unit therein, the shutter unit including a top plate which is partly formed by a movement of a plate member, and a second light shielding BOX having a photodetector therein. While a measurement is not implemented, the shutter unit is closed to block entrance of stray light to the photodetector, and while a measurement is implemented, the plate member is moved to open the shutter unit, and the tip of the photodetector is inserted into a through hole formed in the top plate, so that the distance between the bottom of the sample container and a sensitive area of the photodetector is reduced to several millimeters or less.

A fluorescence detector in which a sample substrate is provided with a structure unit comprising a prism or a diffraction grating. After excitation light falling on the sample substrate is totally reflected at a biomolecule-immobilized face that is located in the opposite side of the structure unit, the structure unit allows the emission of the reflected light therefrom. To ensure multiple visual field measurement, a sample substrate-driving unit is provided to scan the sample substrate.
