Plate reader

A plate reader is a laboratory instrument used to measure the properties of multiple small samples, often contained in a grid of wells called a microplate. It detects signals such as light absorption, fluorescence, or luminescence emitted by the samples, which helps scientists analyze biological and chemical reactions quickly and efficiently. Plate readers are commonly used in research, diagnostics, and drug development to generate data on large numbers of samples simultaneously, saving time and providing precise, reproducible results.
