<p>Unused reaction vessels and unused nozzle tips are arranged in a matrix on a vessel magazine and a tip magazine, respectively. A carrying mechanism for moving a gripping mechanism along X- and Y-axes seizes unused nozzle tips on the tip magazine one by one in order, and transfers them to a tip attaching station. The carrying mechanism also seizes unused reaction vessels on the vessel magazine one by one in order starting from one end of the first row. A delivery mechanism, after having attached a nozzle tip on the tip attaching station to a nozzle holder, pours sample and reagent into a reaction vessel on a delivery station. The reaction vessel is carried by a gripping mechanism to an incubator where the mixture of sample and reagent is incubated. After incubation, the reaction vessel is transferred to a shipper station where the reaction solution is extracted by suction with a shipper nozzle which introduces the solution into the flow cell of a measuring device. Prior to the above analysing operation, the gripping mechanism with its fingers kept closed moves about over the delivery station and the incubator for checking presence of obstacle, and disposes it of if one. <IMAGE></p> |
