The Benchmark E4100 Accuris SmartBlue Blue Light Transilluminators with Amber Cover, 115V Input emits blue light at a wavelength of 465nm, perfect for excitation of most green fluorophores, including Accuris' SmartGlow, as well as many protein stains. Exposing DNA to this wavelength does not cause damage, and results in a much higher downstream cloning efficiency as compared to even short UV light exposures. In addition, the visible blue light is not damaging to the skin and is less harmful to the eyes.

This model includes emission filter covers. These amber covers, which rest above the viewing surface and gel, filter out the blue light, allowing the fluorescent DNA bands to be seen clearly. The covers are designed to fit flat for general gel viewing or to be placed at an angle to provide easy access to the gel for band excision. For documentation, the filter cover is easily removed completely.

The bright LED light plates and filter layer provides an extremely evenly lit viewing surface. Even in ambient light, bands of DNA can clearly be seen in stained gels. Images obtained using the SmartBlue Transilluminator are brighter and more balanced than those obtained using epi-illuminators which light from the sides. An array of super bright LEDs with a long, 30,000 hour service life provide the light source for the SmartBlue Transilluminators. Unlike those in a UV transilluminator, the filters in the SmartBlue systems will not solarize and degrade in performance over time. Gel bands can be excised directly on the scratch resistant, glass viewing surfaces. To save energy, the power switch includes an automatic 5 minute shutoff.
