An ultra-violet (UV) transilluminator is a standard piece of equipment used in life science laboratories for visualization of target DNAs and proteins. The UV transilluminator works by emitting high levels of UV radiation through the viewing surface. The key application for a UV transilluminator is for visualization of DNA and protein agarose and polyacrylamide gels after electrophoresis. Gels can be directly placed onto the UV transilluminator; wavelength will vary on your particular application.

White light transilluminators are used for viewing Coomassie blue or silver stained gels. Uniform white light diffusion enables viewing of autoradiographs, X-ray film, film positives, negatives, and microtiter plates. Plexiglass and glass filter combination are sealed into the unit for durability
