1. An automatic analyzer comprising:
a reagent dispensing mechanism that sucks a reagent in a reagent vessel, and dispenses the sucked reagent to a reaction vessel;
an analyzing unit that analyzes a sample in the reaction vessel;
a storage unit storing a plurality of dead volume setting values of the reagent in the reagent vessel; and
a control unit configured to control operation of the reagent dispensing mechanism, wherein
the control unit is further configured to determine whether an amount of the reagent in the reagent vessel is smaller than one of the plurality of dead volume setting values stored by the storage unit, and to control the reagent dispensing mechanism to stop the sucking of the reagent from the reagent vessel if the amount of the reagent in the reagent vessel is smaller than said one dead volume setting value, and
each of the plurality of dead volume setting values is associated with one of a plurality of wettability levels of the reagent.
