ABSTRACT:
The particle measuring apparatus includes a specimen pipetting section for pipetting a specimen liquid, a reagent dispensing section for dispensing a reagent, a mixing section for receiving the specimen liquid supplied by the specimen pipetting section and the reagent dispensed by the reagent dispensing section and a flow cell for receiving the specimen liquid and the reagent transferred from the mixing section and measuring particles therein; the pipet being so constructed as to be positioned in a first state of picking up the specimen liquid as well as in a second state of supplying the specimen liquid into the mixing section, the mixing section being open when the pipet is in the first state, the mixing section being kept closed by the pipet in the second state so that the reagent dispensed by the reagent dispensing section can press and transfer the specimen liquid in the mixing section out toward the particle measuring section.
