Abstract
A hybrid pipette including a pipette casing ( ) and a slide shaft ( ) vertically movable in response to the operation of a pushbutton ( ). A plunger ( ) is disposed below the slide shaft and urged upwardly by a spring ( ). An engagement member ( ) is coaxially and movably fitted on the slide shaft ( ) and extends through a hole ( ) in a casing member ( ) so as to be movable at least vertically. An electric motor ( ) is provided on an axis different from the axis of the slide shaft and operatively engaged with the engagement member ( ). In a manual operation mode, the slide shaft ( ) and the plunger ( ) move vertically in response to the operation of the pushbutton ( ) to perform suction and discharge of a liquid. In a motor-driven operation mode, the engagement member ( ) is driven to move vertically by the electric motor ( ), whereby the plunger ( ) is moved vertically to perform suction and discharge of a liquid.
