Abstract

There is disclosed a pipette-washing device for use with an automatic biochemical analyzer. The pipette-washing device includes a wash fluid-ejecting block for ejecting a wash fluid toward pipette. An upwardly spreading groove is formed in the top surface of the body of the block and extends along the trajectory of the front end of the pipette. The groove is connected at its lower end with the vertical wash fluid channel. A lateral draining channel is formed in the body of the block and connected with the lower end of the vertical wash fluid channel. When the pipette moves, the front end of the pipette moves through the groove. The block is inclined at an angle to the vertical within a plane in which the groove extends.
