APPARATUS AND PROCESS FOR MEASURING ABSORBANCE IN FLUID SAMPLES

摘要

The device (11) comprising a housing (15) having an exterior surface (21) and an interior surface (23). The interior surface defines a chamber (25) having an input opening (31) and an exit opening defined by rims (33). The input opening has a first geometric shape and the exit opening has a second geometric shape. Any point about the rim at the input end can be connected by a straight line to any point on the rim of the exit end. The interior surface end of the chamber corresponds to the sum of these lines from the rim of the input opening, to the rim of the exit opening.
