PURPOSE:To enhance an efficiency of inspection of specimens by using magnetic bead together with other inspection apparatus by so loading a magnet for magnetically attracting a body for supporting a dispensing head as to be switchable to a near position or to a separate position from a sample vessel. CONSTITUTION:A moving frame 6 for supporting a dispensing head 2 is laterally and vertically movably mounted, and sample liquid is dispensed to a test tube inserted to a rack of a front side of a body 1 by a suction nozzle 20 and a dispensing nozzle 21 communicated with a pump to be sucked. An engaging unit 52 of a magnet 5 is engaged with an engaging groove 72 of a bracket 71, a rotary shaft 70 is forwardly/reversely turned so that a position to the tube is changed over. In the step of cleaning bead after the sample and the bead are dispensed to the tube by the nozzle 21 and reacted, the magnet 5 is alternately approached to and separated from the tube to expedite cleaning of the bead, thereby enhancing an inspection. |
