Abstract
A cup used to receive, hold, measure and pour liquids, such a specimens, such as for a medical assay, is described. The cup comprises an open receiving upper chamber, two or more open sample-directing channels, and an open, calibrated and marked measuring column. When sitting on a level surface, fluid flows freely from the upper chamber through the sample-directing channels into the measuring column. A foot is under each fluid-directing channel. The base of the measuring column functions as an additional, such as a third, foot. Cups nest, with the two feet of the upper cup sitting into two sample-directing columns of lower cup. The measuring column and upper chamber taper to permit nesting. If the cup is tipped, it rests on two of three of: the two feet and the base of the measuring column, and a point on a lower perimeter of the upper chamber, such that fluid will not spill.
