ABSTRACT:
An apparatus for testing a substance is characterized by a substantially planar base member carrying a reservoir extending lengthwise thereon. A plurality of test zones, each having a chemical substance therein, are carried by the base and are disposed in a side-by-side relationship with each other and in a substantially perpendicular relationship with the reservoir. Each test zone is separated and isolated from the next adjacent test zone by a sidewall of a predetermined height. The test zones are each separated from the reservoir by a barrier having a height less than the height of the sidewall. A clear plastic cover is provided to enclose the reservoir and the test zones so that fluid communication is permitted only between each individual test zone and the reservoir through a clearance space defined between the interior of the cover and the top of the barrier. After introduction of the substance to be tested within the reservoir, the method comprises rotating the testing apparatus a predetermined angular distance about an axis of rotation extending longitudinally through the reservoir to permit the substance to be tested into enter each of the test zones through the defined clearance. The testing apparatus may be rotated in an angular direction opposite to the first angular direction to thereby return the apparatus to its original position and isolate the substance to be tested in each individual test zone.
