ABSTRACT:
Apparatus for loading onto a pipettor a plurality of micropipette tips, the pipettor having a plurality of tip pins depending from a head portion, the tips each having an upper, hollow, tapered, generally cylindrical barrel portion and lower, hollow, generally cylindrical aspirating tip portion, both lying along a common vertical axis and being cojoined at a horizontal shoulder, and the tips being frictionally held in a tip package, the apparatus comprising: a horizontal pusher plate to simultaneously engage the shoulder on each of the tips and to simultaneously raise the tips for insertion of the tip pins therein. In a further aspect of the invention, there is provided a micropipette tip package for such tips, the tip package including: a generally hollow housing having four cojoined sidewalls depending from a horizontal cojoined upper surface to define an open skirt; the upper surface having defined therein a plurality of openings to accommodate therein the distal ends of the upper portion of the tips; a horizontal internal supper plate in the housing having defined therein a plurality of openings to accommodate therein the proximal ends of the upper portions of the tips; and corresponding pairs of the openings in the internal support plate and the upper surface being vertically aligned coaxially so that the micropipette tips can be supported in a vertical position in the package and releasably held therein by interference fits.
