Abstract
A microplate forms a multiplicity of sample wells for holding samples to be assayed by light emissions or light transmission. The plate comprises an upper plate forming the side walls of the sample wells, the side walls being opaque so that light cannot be transmitted between adjacent wells through the side walls, and a lower plate forming the bottom walls of the sample wells, the bottom walls being transparent to allow the transmission of light therethrough. Bands of opaque material are provided within the lower plate and surrounding each well to block the transmission of light between adjacent wells through the lower plate.
