Sample analyzer, reagent aspirating method, and computer program product
First Claim
1. A sample analyzer for analyzing a sample using a reagent corresponding to a predetermined analysis item, comprising:
- a table configured to hold a first rack and a second rack, each of the first and second racks comprising a rack identifier and a plurality of reagent container holders, wherein a number of the reagent container holders of the first rack is different from a number of the reagent container holders of the second rack;
a table rotating part configured to move the table;
an aspirator which comprises an aspirating pipette in which a reagent from a reagent container held by a reagent container holder is aspirated and a driver configured to move the aspirating pipette;
an identification information obtainer configured to obtain identification information of a rack holding a target reagent container which contains a target reagent used for analysis, from a rack identifier of the rack;
a controller configured to determine a type of the rack holding the target reagent container based on the identification information obtained by the identification information obtainer, to control the driver so as to move the aspirating pipette to a predetermined reagent aspirating position according to the determined type of the rack holding the target reagent container and to control the table rotating part so as to move the target reagent container to the reagent aspirating position; and
an analyzing section configured to analyze a sample using the target reagent aspirated by the aspirating pipette at the reagent aspirating position.
