Laboratory fluorometers are specialised instruments used to measure the intensity of fluorescence emitted by a sample when excited by specific wavelengths of light. These devices play a crucial role in various scientific applications, including biochemical assays, environmental monitoring, and clinical diagnostics. By using fluorophores—molecules that emit light upon excitation—fluorometers can detect and quantify the presence of specific substances, such as proteins, nucleic acids, or pollutants, within a sample. The sensitivity and specificity of fluorometers make them invaluable for research in fields such as molecular biology, pharmacology, and toxicology. With the capability to provide real-time data, fluorometers enhance the accuracy of experimental results and facilitate in-depth analysis of complex samples.
