Microplate Reader Basics

Many biological assays use bioluminescent, fluorescent or colorimetric reactions to generate a light signal, which must be quantified to interpret the experimental result. If the assay is conducted in a microwell plate, the light output from these assays is measured using a microplate reader (or plate reader). Microplate readers are commonly used in life science laboratories.

Microplate readers may include the ability to detect a single type of light signal, such as fluorescence or luminescence, or may provide more sophisticated capabilities allowing detection of multiple types of signal. Microplate readers capable of detecting multiple signals (such as fluorescence, luminescence and absorbance) are known as multimode readers.
