Abstract: A dispensing apparatus includes a probe that sucks or discharges a liquid; a pressure generating unit that generates a pressure necessary for the probe to suck or discharge the liquid; and a pressure measuring unit that measures the pressure generated by the pressure generating unit and applied to the probe. The apparatus also includes a setting unit that sets a correction coefficient used when correcting a physical amount based on characteristics of the dispensing apparatus using a result of the measuring by the pressure measuring unit; a storage unit that stores therein information including the correction coefficient set by the setting unit; and a correcting unit that corrects the physical amount using the correction coefficient stored in the storage unit.

Abstract: A stirring device (1) capable of correctly detecting abnormality in a stirring process and preventing liquid which has not been stirred in a normal process from being used in an analyzing process, and an analyzer are provided. The stirring device (1) according to the present invention includes a nozzle (2), a syringe (14), and an abnormality detecting section (35) for determining whether or not a stirring process has been performed in a normal manner on liquid, which is a stirring subject, in a stirring container (23), on the basis of the amount of deviation between a suction pressure waveform indicating a suction pressure change measured by a pressure measuring section (6), and a suction pressure waveform pre-obtained during normal stirring.

Abstract: A dispensing device includes a probe that suctions and discharges liquid contained in a vessel; a probe control unit that moves the probe downward in a stepwise fashion by a predetermined amount by controlling a lowering operation of the probe to an inside of the vessel and controls a suction operation and a discharge operation of the probe in each step; a pressure detecting unit that detects a pressure in the probe; a suction-and-discharge-state judging unit that judges a suction state or a discharge state of the liquid by the probe based on a detection result by the pressure detecting unit; and a liquid-surface detecting unit that detects a liquid surface position of the liquid based on a lowering amount of the probe when the suction-and-discharge-state judging unit judges that the probe suctions the liquid or the probe discharges the liquid.
