The transilluminator is a vital tool in the molecular diagnostic laboratory and other molecular biology disciplines. This device, also known as a light box, illuminates agarose or acrylamide gel samples from below to reveal the presence and positions of stained DNA, RNA or protein fragments. 

Within the field of molecular biology and microbiology, the UV transilluminator emerges as an indispensable resource. This specialized equipment provides researchers with the ability to visualize minute details imperceptible to the naked eye, facilitating research and experimental processes.

In scientific experimentation, it is crucial to have adequate laboratory instrumentation. An essential device for visualization of results in gel electrophoresis experiments is the transilluminator.
