摘要： An air displacement pipette having axially spaced annular sealing and lateral support zones and regions on the pipette's mounting shaft and tip, respectively, the annular sealing zone comprising an annular sealing surface outward of an outer surface of the mounting shaft at a lower end thereof and a sidewall of the pipette tip in the sealing region being sufficiently thin as to expand slightly and form an interference fit and air tight seal between the sealing surface and the sealing region when the sealing zone penetrates the sealing region and an outer diameter of the mounting shaft in the lateral support zone being equal to or slightly greater than an outer diameter of the pipette tip in the lateral support region to produce an secondary interference fit or air tight seal between the mounting shaft and pipette tip.

摘要： 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.
