Provided are an automated analyzer for analyzing a substance contained in an unknown sample and a liquid reservoir, the analyzer and the reservoir being capable of saving users' operation without remarkably increasing the number of components. A flow path outlet of an overflow portion of the liquid reservoirs projects closer to the inner circumferential side of a drain flow path than to an inner circumferential surface side of an outer wall of the drain flow path serving as a destination to which liquid overflows. In addition, the flow path outlet projects so as to come into contact with an outer wall of the inner pipe. The flow path outlet of the overflow portion projects into the drain flow path so as to be located below an upper end of the outer wall of the drain flow path.

Disclosed is a fully-automatic chemiluminescence immunoassay analyzer, which comprises a base, a reaction cup conveyance module, a robot-arm sample injection module, an incubation module, a manipulator and transit module, a magnetic-separation cleaning module, and a detection module are mutually independently integrated on the base. The reaction cup conveyance module is used for conveying a reaction cup to a pre-determined position; the manipulator and transit module carries the reaction cup into the incubation module, to incubate the reaction cup for a constant-temperature reaction; the reaction cup in the incubation module is carried to the magnetic-separation cleaning module for magnetic-adsorption cleaning; and the reaction cup after cleaning is carried by the manipulator and transit module to the detection module for detection. A plurality of manipulators and a plurality of transit devices may be disposed as required, to link the mutually independent functional parts of the modules. Further, the instrument may be equipped with detection modules and process modules of various detection platforms, which cooperate with the manipulator and transit module to realize diverse detection in a table-top production line manner.

A method for performing a magnetic separation procedure that includes transporting a receptacle containing a fluid medium to a first location of a system, where the fluid medium contains both a sample material and a suspension of magnetically-responsive solid supports. At the first location, the fluid medium is exposed to a first magnetic field for a first dwell period, thereby isolating the solid supports within the receptacle, where no portion of the fluid medium is removed from the receptacle at the first location. The receptacle is then transported from the first location to a second location of the system, where the fluid medium is exposed to a second magnetic field for a second dwell period. Following the second dwell period, at least a portion of the fluid medium is removed from the receptacle. A suspension fluid is then dispensed into the receptacle, and the contents of the receptacle are agitated to suspend the solid supports within the suspension fluid.
