These UV Transilluminators offer an ultra-violet light source for the analysis of fluorescently stained electrophoresis gels. Available in 21x21cm and 21x26cm sizes, these transilluminators are supplied either as standalone units or with the microDOC, as part of a fully integrated gel documentation system. With a large surface area, each transilluminator serves as the perfect workstation for viewing and working with fluorescently-stained protein and nucleic acid gels. Standard features include a high/low intensity safety switch and an efficient starter that allows each of the six 8-Watt UV tubes to energise quickly without flickering, while special filter glass minimises unwanted background light. All of these features maximise contrast and sensitivity, allowing even the faintest fluorescent gels to be viewed. Two dual wavelength models offer added flexibility and convenience. The 312nm wavelength model is recommended for standard gel documentation requirements, while 254nm wavelength models will cause more DNA damage and are suited to other applications such as crosslinking. 254nm bulbs may also be visible through the filter making them unsuitable for gel documentation.
