摘要： An apparatus, system, and method for performing an efficient luminescence measurement are disclosed. The apparatus comprises a nozzle for dispensing a luminescent reagent into a well W in a microplate M, a luminescence measurement unit for measuring luminescence occurring in the well W caused by mixing of the luminescent reagent and a specimen, and a stage (moving unit) for moving the nozzle and the luminescence measurement unit together vertically and horizontally, wherein the nozzle is secured to the stage and the luminescence measurement unit is mounted to be movable vertically with respect to the stage through a holder and springs interposed between the luminescence measurement unit and the holder.

摘要： A luminometer apparatus includes, inside a light-shielded room, a container rack loaded with holding containers, a dispensation mechanism that dispenses a liquid, a rotary plate that turns, while holding a plurality of reaction containers which accommodate a mixture liquid of a sample and a luminescent reagent on a concentric annular plate, and is provided with a gap allowing the container rack to pass therethrough between at least a pair of adjacent ones of the reaction containers, and a photodetection unit that performs luminescence measurements. The light-shielded room has an insertion opening having a width allowing for insertion of the container rack and provided to be openable and closable. The rotary plate is provided with a region in which the container rack can be installed inside a region of passage of the reaction containers, when turning, and is provided to be turnable where the light-shielded room is in a closed state.

摘要： 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.
