Transilluminator

Transilluminators are essential laboratory equipment designed for visualizing fluorescent samples, commonly used in molecular biology, genetics, and forensic science. These devices emit ultraviolet (UV) or blue light to excite fluorescent dyes bound to nucleic acids or proteins, making them visible against a dark background. This visualization is crucial for applications such as gel electrophoresis, where researchers can observe and document the results of DNA, RNA, and protein separation.

The standard transilluminator consists of a flat surface equipped with a light source that shines upwards through a transparent protective cover. Samples placed on the surface absorb light and re-emit it at longer wavelengths, producing a visible glow that can be captured by imaging systems. Advanced models may include features like adjustable intensity settings, multiple wavelength capabilities, and built-in filters to enhance image quality and safety.
