ABSTRACT:
A method of syringing reaction beads in examination of blood or the like comprises the steps of pouring a syringing liquid from a supply nozzle into a flask containing a reaction bead, withdrawing the syringing liquid with a suction nozzle to end the syringing of the beads and subsequently withdrawing the remaining syringing liquid in the flask with the suction nozzle on one side of the interior of the flask by blowing air from an air jet nozzle into the other side of the flask interior. An apparatus for syringing the reaction beads comprises a suction nozzle, a supply nozzle and an air jet nozzle or a supply/air jet nozzle provided such that they depend from a supply head and face the flask provided on a table below the supply head, free end portions of the suction nozzle and air jet nozzle being disposed on one side of the interior of the flask and on the other side of the interior of the flask, respectively.
