    Abstract: A volume adjustable pipette (30) for aspirating and dispensing precise volumes of liquid comprising an elongated hollow hand-holdable housing (32) supporting a plunger (34) for turning and for axial movement within the housing. The pipette includes an upper stop (40) which is axially adjustable within the housing in response to a turning of the plunger to adjust the volume of liquid which may be drawn into a tip (1b) secured to a lower end of the housing upon upward axial movement of the plunger to the upper stop. The pipette further includes a manually actuated lock mechanism (48) for locking the plunger against rotation to set the volume adjustment for the pipette. The lock mechanism comprises a hand-turnable knob (50) for actuating and releasing the lock mechanism by virtue of two thumb and/or finger engageable wings (68a, 68b) extending outwardly from diametrically opposite sides of the hand-turnable knob. A thumb and/or finger turning force exerted on the wings in one direction effects an actuation of the lock. A thumb and/or finger turning force exerted on the wings in an opposite direction effects a release of the lock. The lock further comprises a gripping member (62) for fixedly securing the plunger against turning. A gripping member is actuated by a turning of the hand-turnable knob to force a cam surface of the knob against a cam surface of the gripping member.

    Abstract translation: 一种用于抽吸和分配精确体积的液体的体积可调移液管（30），包括支撑用于转动并在壳体内轴向运动的柱塞（34）的细长的中空手持式壳体（32）。 移液管包括上部止动件（40），其可响应于柱塞的转动而在壳体内可轴向调节，以调节液体的体积，该液体的体积可以被拉入到固定到壳体的下端上的尖端（1b） 柱塞向上止动件的轴向运动。 移液管还包括用于锁定柱塞以防止旋转以设定移液管的体积调节的手动致动的锁定机构（48）。 锁定机构包括用于通过从手动转动旋钮的直径相对侧向外延伸的两个拇指和/或手指可接合的翼（68a，68b）来致动和释放锁定机构的手动转动旋钮（50）。 在一个方向上施加在翼上的拇指和/或手指转动力影响锁的致动。 以相反方向施加在翼上的拇指和/或手指转动力影响锁的释放。 所述锁还包括用于固定地固定所述柱塞以防转动的夹紧构件（62）。 握持构件通过手动转动旋钮的转动而致动，以将把手的凸轮表面压靠在夹持构件的凸轮表面上。

    Abstract: A pipette tip ejector mechanism for a pipette (12) comprising a releasable connector (42) between a lower end of an ejector shaft (20) and an upper end of an ejector arm (40). The connector has a female receptor (44) and a male connector (46) which can be adapted to fit either the shaft (20) or arm (40). A cantilever (48) carries a locking member (50) or a locking shoulder (52) to engage and lock a respective shoulder (52) or member (50) on the shaft (20) or arm (40). The cantilever (48) also carries a tab (54) extending outwardly for finger engagement by a user to move the cantilever (48) for disengaging the locking member (50) from the locking shoulder (52), allowing the arm (40) to be separated from the shaft (20) of the pipette (12) for cleaning, service, replacement, or use of the pipette (12) without the arm (40).
