ABSTRACT:
A washing apparatus for washing a probe which is transferred substantially horizontally in a plane during a washing process includes a washing body having a wall structure defining an inner hollow portion, a feed water unit provided for the wall structure of the washing body for feeding water in the inner hollow portion, slits formed in the wall structure of the washing body so as to communicate with the inner hollow portion of the washing body, and at least a first waterway channel having one end connected to a bottom portion of at least one of the slits and a second, free end, wherein the waterway channel is disposed on a level substantially corresponding to a transfer route of a tip of the probe and has a shape so as to substantially correspond with the transfer route of the probe. The waterway channel is formed so that the tip of the probe is most deeply dipped at a portion near the one end of the waterway channel connected to the slit of the washing body and then is separated from the waterway channel at a portion near the free end of the waterway during the horizontal transfer of the probe. The probe washing apparatus can be utilized particularly for a random access type automatic analysis system for washing the probe after suction of a sample or reagent into the probe before reaching a reaction tube.
