This high performance transilluminator provides high intensity and uniform UV illumination. The unique design of these transilluminators provices increased performance and efficiency. Product enhancements include a new electronic ballast and cutting-edge construction. Additional featured inclued zero light flicker, a wider UV intensity range with variable selection, fast lamp start up and a universal power supply. These transilluminators feature a stainless steel cover frame which provides an easy-to-clean surface and reduces cross contamination of samples. Uniform, brilliant back-lit fluorescence illumination is enhanced with UVP's unique background uniformity screen and UVG long-life filter. A uniformity screen is available on units with midrange or longwave UV. The transilluminator's powerful cooling fan maintains a low filter surface temperature to prevent sample damage and maintains a constant UV intensity. A removable and adjustable protective UV blocking cover is also included with each transilluminator. Variable intensity settings (high/medium/low) - high setting allows for UV excitation of fluorophores on gels for routine photography. Medium is excellent for viewing and quick single-band excision. Low setting allows for positioning and preparation of gels, excising multiple bands, and focusing for photography. Improved gel visualization and gel documentation. Designed for use with high fluorescence and sensitivity on stained gels. Two-year warranty. CSA certified.
