Fluorometers are measurement instruments that detect and quantify the fluorescence emitted by biological and chemical samples. They use a light source, usually a laser or LED, to excite the fluorescent molecules in a sample. The light emitted by these molecules as they return to their ground state is captured and measured, providing precise data on the concentration and presence of various compounds.
