Pipette tip handling device assembly

Abstract

Description

FIG. 1 shows an exploded perspective view of a pipette tip handling device assembly of the present invention. From top to bottom, the individual components are identified as an actuator housing, actuator plate, pipette tips, distal barrier plate, alignment housing, and loading block. The ellipsis markings indicate the presence of a full complement of pipette tips where the full complement of pipette tips were omitted for clarity of illustration. The full complement of pipette tips, as shown in FIG. 2, form part of the claimed design;

FIG. 2 shows an exploded perspective view as seen in FIG. 1 of a pipette tip handling device assembly of the present invention with a full complement of pipette tips added for illustrative purposes;

FIG. 3 shows an enlarged side elevation view of a pipette tip of the pipette tip handling device assembly shown separately for clarity of illustration. Pipette tip(s) is/are shown in FIGS. 1, 2, 5-11, 15 and 16 with partial views thereof in FIGS. 4, 13 and 14;

FIG. 4 illustrates a cross section of the pipette tip of FIG. 3 taken along lines 4-4 or FIG. 3;

FIG. 5 shows a perspective view of an assembled pipette tip handling device assembly of FIG. 1. The ellipsis markings indicate the presence of a full complement of pipette tips where the full complement of pipette tips were omitted for clarity of illustration. A full complement of pipette tips, as shown in FIG. 2, form part of the claimed design;

FIG. 6 is a cross sectional view taken along line 6-6 of the pipette tip handling device assembly of FIG. 5. From top to bottom, the individual components are identified as an actuator housing, actuator plate, pipette tips, distal barrier plate, alignment housing, and loading block. The ellipsis markings indicate the presence of a full complement of pipette tips where the full complement of pipette tips were omitted for clarity of illustration. A full complement of pipette tips form part of the claimed design;

FIG. 7 is a cross sectional view taken along line 7-7 of the pipette tip handling device assembly of FIG. 5 with a full complement of pipette tips added for clarity of illustration;

FIG. 8 shows the view of FIG. 7 after the actuator has been fully actuated. From top to bottom, the individual components are identified as an actuator housing, actuator plate, distal barrier plate, alignment housing, and loading block comprising pipette tips. The ellipsis markings indicate the presence of a full complement of pipette tips where the full complement of pipette tips were omitted for clarity of illustration. A full complement of pipette tips form part of the claimed design. In the fully actuated state as shown, some ejected pipette tips have been removed for clarity of illustration;

FIG. 9 shows a side elevation view of a pipette tip as shown in FIG. 3;

FIG. 10, taken from FIG. 7, shows an enlarged cross sectional view of nested pipette tips of the pipette tip handling device assembly with the bottom pipette tip positioned for loading into the loading block;

FIG. 11, taken from FIG. 7, shows an enlarged cross sectional view of nested pipette tips of the pipette tip handling device assembly showing a condition of use where the bottom pipette tip is fully inserted into the loading block;

FIG. 12 is a perspective view of a loading block portion of a pipette tip handling device assembly shown separately for clarity of illustration;

FIG. 13 shows a distal nozzle of a pipettor engaging a proximal port of a pipette tip in a loading block portion of FIG. 12;

FIG. 14 shows multiple nozzles of an automated manifold engaging multiple pipette tips in a loading block portion of FIG. 12;

FIG. 15 shows the cross sectional view of FIG. 6 with the addition of a second alignment housing situated between the actuator housing and first alignment housing. From top to bottom, the individual components are identified as an actuator housing, actuator plate, pipette tips, first alignment housing, pipette tips, distal barrier plate comprising pipette tips, second alignment housing, and loading block. The ellipsis marking indicates the presence of a full complement of pipette tips where the full complement of pipette tips were omitted for clarity of illustration. A full complement of pipette tips, as shown in FIG. 2, form part of the claimed design;

FIG. 16 shows the pipette tip dispensing device of FIG. 15 in a fully actuated, compressed state. From top to bottom, the individual components are identified as an actuator housing, actuator plate, first alignment housing, distal barrier plate, second alignment housing, and loading block comprising pipette tips. The ellipsis marking indicates the presence of a full complement of pipette tips where the full complement of pipette tips were omitted for clarity of illustration. A full complement of pipette tips form part of the claimed design. In the fully actuated state as shown, some ejected pipette tips have been removed for clarity of illustration;

FIG. 17 shows a bottom perspective view of a distal barrier plate portion of a pipette tip handling device assembly;

FIG. 18 shows an enlarged cut away view of FIG. 17;

FIG. 19 shows a cross sectional view taken along line 19-19 of FIG. 17 thereof;

FIG. 20 shows an enlarged cut away cross sectional view taken from FIG. 20 of one channel;

FIG. 21 shows a bottom view of a distal barrier plate portion of a pipette tip handling device assembly;

FIG. 22 shows an enlarged partial view of FIG. 21; and,

FIG. 23 shows a side view of the distal barrier plate, where the tails are varied in length.

Broken lines, where utilized, are for illustrative purposes only, are not part of the claimed invention, and do not limit the claimed design to the features shown in broken lines. The broken lines are included for the purposes of illustrating unclaimed portions of the pipette tip handling device assembly and form no part of the claimed design.
