1. A reagent tube for insertion into a tube holder strip, comprising:
- a tube body having a top, a bottom, and an interior surface, wherein the top, bottom, and interior surface of the tube body define a volume configured to hold a liquid;
a radially-extending lip at the top of the tube body configured for locking engagement with cooperating structure on a tube holder strip to retain the tube after insertion into a tube holder strip;
a pattern of convex ridges extending radially and centered at the bottom of the interior surface of the tube, wherein the convex ridges extend vertically from the bottom interior surface of the tube body, wherein the pattern of ridges and the ridges are configured to enable pipetting of substantially all of the liquid held in the reagent tube; and
a ring centered at the bottom of the interior surface of the tube, wherein the pattern of radially extending convex ridges intersect the ring.

Abstract
A reagent tube configured with a stellated shaped pattern, on its bottom interior surface, configured to facilitate complete or near-complete withdrawal of fluid from the tube, via a pipette tip. The reagent tube may be used for transporting reagents and for carrying out processing operations on biological samples with the reagents, such as preparing polynucleotides extracted from the sample for amplification.

28. A reagent tube for insertion into a tube holder strip, comprising:
-
a tube body having a top, a bottom, and an interior surface, wherein the top, bottom, and interior surface of the tube body define a volume configured to hold a liquid; a radially-extending lip configured for locking engagement with cooperating structure on a tube holder strip to retain the tube after insertion into the tube holder strip, the lip comprising a top surface proximal to the top of the tube body, a bottom surface opposite the top surface, a radial wall extending between the top and bottom surface of the lip, and a beveled edge located at the junction of the top surface and the radial wall; a pattern of convex ridges extending radially and centered at the bottom of the interior surface of the tube, wherein the convex ridges extend vertically from the bottom interior surface of the tube body, wherein the pattern of ridges and the ridges are configured to enable pipetting of substantially all of the liquid held in the reagent tube; and a ring centered at the bottom of the interior surface of the tube, wherein the pattern of radially extending convex ridges intersect the ring.
