  • Patent number: 6165739
    Abstract: A stationary testing media device made of a glass or plastic plate and conveniently a microscope slide, wherein multiple simultaneous tests are conducted on a single multifurcated testing sample. The plate or slide is partitioned into two or more testing zones with each of the zones having been preferably pre-loaded with a stable test reactant. The testing zones are physically separated from one another but are connected, with a fluid flow connection, to a single sample reservoir which simultaneously feeds, such as by capillary action, each of the testing zones with a test portion of the testing sample. The testing zones retain the individual portions for a time sufficient to effect the individual zone reactions with pre-loaded reagents. An optional outflow reservoir is utilized to capture excess sample flow and flushing fluids.
