Bilaterally symmetrical battery powered microprocessor controlled lightweight hand-holdable electronic pipette

A bilaterally symmetrical light weight microprocessor controlled electronic pipette holdable in either the right or left hand of a user with the thumb of user's hand holding the pipette free to actuate forwardly facing control keys to set the operation of the pipette and trigger switches to actuate operation of the pipette while viewing a forwardly facing display, the pipette comprising:

• an axially elongated hollow housing having a vertically extending longitudinal axis and including vertically extending and substantially coaxial upper and lower portions;
• the upper portion of the housing including a forward compartment and a rearward compartment,
• the forward compartment containing
• a forwardly facing alpha-numeric display adjacent a top of the housing,
• a plurality of columns of forwardly facing pipette operation setting control keys and
• a plurality of forwardly facing pipette operation actuating trigger switches below the columns of control keys,
• the display, columns of control keys and trigger switches being bilaterally symmetrical relative to the longitudinal axis of the housing, and
• the rear compartment containing a replaceable battery for powering a microprocessor and motor contained within the housing;
• the lower portion of the housing comprising a vertically elongated handle coaxial with the longitudinal axis of the housing and having contiguous bilaterally symmetrical and vertically extending forward and rear portions for hand gripping by the user of the pipette,
• the forward portion of the handle extending forward of the upper portion of the housing and extending vertically downward to a lower end of the housing, and
• the rear portion of the handle extending rearward from the forward portion of the handle and having a hook extending rearward from a back of an upper end of the handle and having a downwardly curved lower surface for engaging an upper side of an index or middle finger of the user while the user is gripping the handle with the thumb of the user free to actuate any of the bilaterally symmetrical control keys and trigger switches in any sequence desired while clearly viewing the alpha-numeric display as it responds to the actuation of the control keys and trigger switches,
• the hook, forward and rear portions of the handle all being bilaterally symmetrical relative to the longitudinal axis of the housing.
