ABSTRACT:
There is described a fluid dispensing system which includes a pipette assembly adapted for use with disposable pipette tips. To ensure a precise location of a disposable pipette tip on the distal end of the stem of the pipette assembly which holds the pipette tip, a proximal chamber of the pipette tip envelops the distal end of the stem and includes a ledge which encircles an annular region of the stem to form an abutment for the stem and establish a precise distance between the distal end of the stem and the pipette tip orifice. In a preferred embodiment the fluid dispensing system is incorporated in an automated analytical instrument.
