  • Patent number: 6027695
    Abstract: An apparatus for holding liquid, such as a microtiter plate, in which a plurality of wells are formed. Each of the wells have side walls that intersect in an edge that defines the boundary between adjacent wells. The edge boundary prevents liquid from collecting between the wells, thereby causing all of the liquid applied to the plate to enter one of the wells. The microtiter plate can be formed from a material having a reflectance and/or fluorescence that is optimized for the particular application in which the microtiter plate will be used. Microtiter plates for use in fluorescence measurement applications are made from material having low fluorescence, such as a liquid crystal polymer, while microtiter plates for use in luminescence measurements are made from material having a high reflectance. Microtiter plates for spectrophotometric applications are made with wells having clear bottoms and opaque walls.
