Patent ID: 8343423

Claim:
An automatic analyzer comprising: a plurality of reaction vessels, a plurality of parent sample vessels, a plurality of reagent vessels, and a plurality of diluted sample vessels; a rotatable reaction disk for rotating said reaction vessels arranged on said reaction disk about an axis of said reaction disk, each of said reaction vessels receiving a sample and a reagent; a photometer for measuring a sample received in one of said reaction vessels on said reaction disk; a parent sample vessel holding unit for holding said parent sample vessels, each of which receives a parent sample; a reagent disk on which said reagent vessels are arranged, each of said reagent vessels receiving a dilution reagent used to dilute a sample or an analysis reagent used to analyze a sample; a rotatable diluted sample disk for rotating said diluted sample vessels arranged on said diluted sample disk about an axis of said diluted sample disk, each of said diluted sample vessels receiving a diluted sample diluted from a parent sample by a dilution reagent; a parent sample pipetting probe for dispensing a parent sample into said diluted sample vessel arranged on said diluted sample disk from said parent sample vessel arranged on said parent sample vessel holding unit; a reagent pipetting probe for dispensing a diluted reagent into said diluted sample vessel arranged on said diluted sample disk from said reagent vessel arranged on said reagent disk; a diluted sample pipetting probe for dispensing a diluted sample into said reaction vessel from said diluted sample vessel arranged on said diluted sample disk, and said diluted sample pipetting probe sucking out a diluted sample from said diluted sample vessel and discarding said diluted sample; an operation unit having a display unit configured to display a conditions setting screen including diluted sample hold and discard conditions, said conditions setting screen configured to set items to be measured by said photometer with respect to said samples and said analysis reagents, said conditions setting screen configured to apply measurement instructions for said photometer with respect to said samples and said analysis reagents, and said conditions setting screen configured to set a timing for discarding a specific diluted sample from said diluted sample vessel on said diluted sample disk; and a control unit configured to control rotation of said reaction disk and said photometer to analyze and inspect a sample in accordance with said measurement instructions from said operation unit, said control unit further configured to control rotation of said diluted sample disk and said diluted sample pipetting probe to suck out said specific diluted sample from said diluted sample vessel on said diluted sample disk by said diluted sample pipetting probe and to discard said sucked specific diluted sample at said timing set with said conditions setting screen.
