The ornamental design for a pipette tip, as shown and described.

FIG. 1 is a front perspective view of a pipette tip showing my new design;

FIG. 2 is a side elevational view thereof, the undisclosed sides being identical;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof; and

FIG. 5 is a cross-sectional view thereof, taken on line 5--5 of FIG. 4.

The characteristic feature of the design resides in the four concentric ridges found on the interior surface of the pipette tip immediately below and within the bell top as illustrated in FIGS. 1, 2 and 5 and the six vertical ribs evenly spaced along the bell top.

Williams, Fred G.
