Patent ID: 6987563

Claim:
A luminescence validation microplate for testing the validity of a luminescence microplate reader comprising a microplate having a plurality of wells with a backlight panel having a fixed light output, positioned behind said wells, said wells consisting of: a) a first set of measurement positions in a 3×3 grid suitable for performing a cross-talk one-in-eight test wherein the center position is a well in light emission contact with the backlight panel and the surrounding 8 grid positions do not contain a well or contain a well that is not in light emission contact with the backlight panel; b) a second set of measurement positions in a 3×3 grid suitable for performing a cross-talk eight-around-one test wherein the center position does not contain a well or contains a well that is not in light emission contact with the backlight panel and the surrounding 8 positions each contain a well in light emission contact with the backlight panel; c) a third set of measurement positions wherein each position consists of a well in light emission contact with the backlight panel and is suitable for performing a linearity test wherein each well of said set is fitted with a neutral density filter of different ability to pass light from the backlight panel or fitted with the same neutral density filter wherein each well in the set is of decreasing diameter; d) a fourth set of wells suitable for performing an alignment test wherein each well of the fourth set is the same size and in light emission contact with the backlight panel.
