Document Type and Number:
Japanese Patent JP3881551
Kind Code:
B2
Abstract:
A volume adjustable manual pipette having a hand-holdable housing supporting (i) an electronic digital display and associated position sensing and control circuitry, (ii) a plunger unit and (iii) a quick set volume adjustment mechanism for simultaneously controlling the volume setting of the pipette and the electronic display, the quick set volume adjustment mechanism comprising a pipette volume setting member for limiting upward movement of the plunger unit within the housing to define the volume setting for the pipette and the volume setting member being supported for axial movement on the plunger unit and releasably secured relative to the housing by a pipette user operable locking mechanism. When released from the housing, the volume setting member is axially moveable on and with the plunger unit to quickly set the volume for the pipette. When secured to the housing, the plunger unit is axially moveable relative to the volume setting unit to aspirate and dispense the selected volume of liquid into and from a pipette tip extending from a lower end of the housing. The volume setting of the pipette is monitored by the sensing and control circuitry to provide a real time display of the volume setting of the pipette.
