Luminescence detection apparatus

A luminescence detection apparatus comprising:

• a plurality of reaction cells each having a substantially transparent bottom portion;
• a solution-dispensing portion equipped with a plurality of capillaries positioned above said reaction cells and put into a one-to-one correspondence with said reaction cells;
• and a light-detecting portion having a plurality of light-sensing elements put into a one-to-one correspondence with said reaction cells and arranged in proximity to the bottom surfaces of said reaction cells, wherein the light-sensing elements of said light-detecting portion detect respective luminescences in said reaction cells generated by injecting reagent solutions from said solution-dispensing portion to said reaction cells,
• said solution-dispensing portion comprising:
• a plurality of reagent containers containing reagent solutions;
• said plurality of capillaries communicating with said plurality of reagent containers;
• a pressure source pressurizing the insides of said plurality of reagent containers;
• and a passage allowing said plurality of reagent containers to communicate with said pressure source, and
• wherein reagent solutions are equally dispensed through discharge nozzles of said plurality of capillaries into said plurality of reaction cells by constant-pressure liquid delivery of pressurizing the insides of said plurality of reagent containers by said pressure source for a predetermined time period.
