Abstract

Provided herein is a single-walled pipette tip rack for use in automated systems, in some embodiments.

First claim

What is claimed is:

1. A single-walled pipette tip rack base, comprising:
a bottom and base sidewalls;
each of which base sidewalls comprises an exterior sidewall surface, an interior sidewall surface, and one or more buttresses;
each of which buttresses is bossed and projects from an exterior sidewall surface;
a ridge, portions of which ridge are substantially co-extensive with each buttress face;
one or more lips in connection with the ridge, each of which one or more lips projects from the ridge away from the base interior, wherein one or more of the lips comprise lip connectors configured to receive a connector of a lid; and
a plate comprising a plurality of plate bores configured to substantially immobilize a pipette tip.

2. The base of claim 1 , comprising flanges, wherein the flanges are integrated with a sidewall and a buttress and comprise a proximal surface and a distal surface.

3. The base of claim 2 , wherein each of the flanges are integrated with two buttresses.

4. The base of claim 3 , wherein the two buttresses are on one base sidewall.

5. The base of claim 1 , wherein each base sidewall comprises two buttresses.

6. The base of claim 1 , wherein each of the buttresses comprises a buttress face, two opposing buttress sidewalls and a buttress bottom.

7. The base of claim 6 , wherein each buttress sidewall comprises a buttress sidewall edge resulting from the buttress sidewall projecting further from a base sidewall than the buttress face.

8. The base of claim 1 , wherein adjacent buttresses on adjoining sidewalls are setback buttresses.

9. The base of claim 1 , comprising flanges, wherein the flanges comprise a flange connector configured to receive a connector of a tray.

10. The base of claim 1 , wherein the base bottom comprises a bottom interior surface comprising wells, wherein the wells are recessed in the bottom interior surface.

11. The base of claim 10 , wherein the bottom interior surface of the base comprises a wall or a ridge around the perimeter of each the wells.

12. The base of claim 1 , wherein each base sidewall has a maximum thickness of about 1 mm or less.

13. The base of claim 1 , wherein the base sidewalls are configured to withstand a compressive pressure equal to or less than about 120 pounds per square inch.
