A fluorometer is an accurate instrument designed to detect fluorescence in a sample of biological material, including cells, DNA, proteins and other parameters. Fluorescence is an emission of light detected by the fluorometer that occurs when an energy source, such as ultraviolet light, is applied to the sample being analyzed. This specially emitted light allows the presence of specific molecules to be detected.
These devices are widely used to detect a variety of biological parameters, such as DNA or protein content in an aqueous solution. These devices can also be used to detect any changes in DNA, allowing the scientist to perform experiments to determine the mutation of a gene sequence.
