1. A device for holding a sample, comprising:
a holder including an upper member attached to a lower member to form a well having a side wall region and a floor, the side wall region extending from a top border to the floor and widening toward the floor at a position intermediate the top border and the floor to create a distinct edge that conceptually divides the well into an upper portion and a lower portion, the well including a side wall protrusion defined by the upper member and adapted to promote wicking of an aqueous sample into the lower portion from the upper portion, the holder defining a channel communicating with the lower portion of the well and with a channel junction that provides a droplet generator; wherein the side wall protrusion is contiguous with the edge.
