    摘要： A plurality of large maximized internal volume freely nestable pipette tips for mounting in a standard pipette tip rack or refill pack including a horizontally extending pipette tip support having a plurality of through holes arranged in an array, each hole having a center which is spaced a distance "s" from centers of immediately adjacent through holes, each pipette tip having a substantially cylindrical proximal portion and an elongated generally conical distal portion coaxial with and joined to its proximal portion adjacent a downward facing outwardly extending shoulder and including at a distal end of the tip a relatively small orifice for receiving and dispensing fluid into and from the pipette tip upon operation of a pipette to which the pipette tip is mounted, the proximal portion of each pipette tip having an outer diameter equal to or slightly less than "s" and a slightly conical inner surface for tightly receiving and releasably attaching to a pipette tip mounting shaft of a large volume pipette and the distal portion of each pipette tip in a first array of tips being vertically oriented in a different one of the through holes in the support with its shoulder on a top of the support.

    摘要： A bilaterally symmetrical lightweight hand holdable battery powered microprocessor controlled electronic pipette including an axially elongated hollow housing having a vertically extending longitudinal axis. An upper portion of the housing includes a forward compartment containing a forwardly facing alpha-numeric display, a plurality of columns of forwardly facing control keys and plurality of forwardly facing trigger switches arranged in a vertically spaced pattern such that a user in gripping a lower handle portion of the housing in either his or her right or left hand can easily reach with his thumb the control keys, trigger switches as well as a push button of a pipette tip ejector.
