    摘要： 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.

    摘要： A pipette tip ejector mechanism for a pipette comprising a releasable connector between a lower end of a pipette tip ejector shaft and an upper end of a pipette tip ejector arm. The connector comprises a female receptor extending from either the shaft or arm and a male connector extending from the other of the shaft or arm to axially fit into the female receptor for support thereby. A cantilever is secured at one end to either the shaft or arm to extend along an outer surface thereof. The cantilever carries one of a locking member or a locking shoulder to engage and lock to the other of the locking member or locking shoulder on the shaft or arm to axially lock the arm relative to the shaft as the male connector is inserted into the female receptor. The cantilever also carries a tab extending outward for finger engagement by a user to outwardly move the cantilever to disengage the locking member from the locking shoulder and to thereby release the arm for axially movement relative to the shaft to allow the arm to be separated from the shaft of the pipette for cleaning, service, replacement or operation of the pipette without the ejector arm which allows access to smaller vessels.
