Patent ID: 7097808

Claim:
A dispensing device to be employed in an automatic analyzer configured to cause a sample and a reagent to react with each other, comprising: a plurality of reagent vessels, each of which stores a reagent; a reagent dispensing section configured to execute a dispensing operation, including aspirating the reagent from one of said plurality of reagent vessels and discharging the reagent into a reaction vessel; a memory storing a plurality of parameter sets for respective reagents, each parameter set associated with a respective reagent and including at least a reagent dummy volumetric amount parameter defining a reagent dummy amount, wherein the plurality of parameter sets include different reagent dummy volumetric amounts; and a controller configured to retrieve one of the plurality of parameter sets associated with a specified reagent from the memory, and configured to control the dispensing operation for the specified reagent to respective reaction vessels based on the parameter set retrieved from the memory.
