Reagent vessels

摘要

Described herein is a stack (10) of a plurality of substantially identical cup-like vessels (20) pre-incorporated with reagent on the inside, each of the vessels (20) occupying at least 50% of the depth of the next adjacent vessel to maximize stacking density. Because the pre-incorporated reagent overlaps the occupied depth portion of the vessel and therefore runs a risk of being dislodged, the wall of the vessel is constructed to provide a gap (X1) between the inside surface (26) bearing the reagent, and the outside surface (28) of the occupying, nested vessel, which is at least 0.025mm.
