For the detection of DNA, stained with Ethidium Bromide, UV-Transilluminators are still widely used. The achievable sensitivity is strongly dependent on the quality of the UV lamps and of the filter material. High quality UV tables show almost no visible light. The quality of the UV light source and of the filter can easily be tested: UV light is invisible to the human eye.
When the instrument is switched on and the position of the UV lamps are easy to detect, too much of the long wavelenght light will be emitted and the result is a much lower sensitivity (see figure below).
The FastGene® UV Transilluminator passes this test without a problem.
Furthermore the FastGene® UV Transilluminator includes a specifically manufactured filter system and shows a very effective protection against harmful UV radiation (see figure below)
