Microplate forming wells with transparent bottom walls for assays using light measurements
First Claim
1. A microplate forming a multiplicity of sample wells for holding samples to be assayed by light emissions or light transmission, said plate comprisinga unitary upper plate forming the side walls of the sample wells, said side walls being opaque so that light cannot be transmitted between adjacent wells through said side walls,a unitary lower plate forming the bottom walls of the sample wells, said bottom walls being transparent to allow the transmission of light therethrough, said bottom walls having respective upper surfaces, andbands of opaque material surrounding the bottom wall of each well and located below a level of the upper surface of the bottom wall of each well, said bands of opaque material constructed and arranged to block the transmission of light between adjacent wells through said lower plate.

Abstract
A microplate forms a multiplicity of sample wells for holding samples to be assayed by light emissions or light transmission. The microplate comprises a unitary upper plate and a unitary lower plate. The unitary upper plate forms the side walls of the sample wells, while the unitary lower plate forms the bottom walls of the sample wells. The side walls are opaque so that light cannot be transmitted between adjacent wells through the side walls. The bottom walls are transparent to allow the transmission of light therethrough. Bands of opaque material surround the bottom wall of each well and are located below a level of an upper surface of, the bottom wall of each well. The bands of opaque material are constructed and arranged to block the transmission of light between adjacent wells through the lower plate.

14. A microplate forming a multiplicity of sample wells for holding samples to be assayed by light emissions or light transmission, said plate comprising
a unitary upper plate forming the side walls of the sample wells, said side walls being opaque so that light cannot be transmitted between adjacent wells through said side walls, a unitary lower plate forming the bottom walls of the sample wells, said bottom walls being transparent to allow the transmission of light therethrough, and grooves formed in the upper surface of said lower plate and surrounding the bottom wall of each well, said grooves being filled with opaque material to block the transmission of light between adjacent wells through said lower plate.

17. A microplate forming a multiplicity of sample wells for holding samples to be assayed by light emissions or light transmission, said plate comprising
a unitary upper plate forming the side walls of the sample wells, said side walls being opaque so that light cannot be transmitted between adjacent wells through said side walls, a unitary lower plate forming the bottom walls of the sample wells, said bottom walls being transparent to allow the transmission of light therethrough, and opaque material disposed at a surface of said lower plate between adjacent wells and beneath a level of an upper surface of the bottom wall of each sample well so as to reduce the transmission of light between the adjacent wells through said lower plate.
