‘Two-in-One’ Transilluminators Provide Both Ultraviolet and White Light Illumination

Spectroline’s transilluminators for designed dual-light convenience in one unit. They are built to exacting standards and are specifically engineered for visualisation of target DNAs and proteins. They work by emitting high levels of UV radiation through the viewing surface.

The advanced Spectroline® Bi-O-Vision™ Series transilluminators feature two workstations, producing both 312nm ultraviolet and white light. The TD-1000R model offers fixed-intensity while the TVD-1000R model offers variable-intensity control of either UV or white light. These units are continuously adjustable from 100% down to 50%. This enables researchers to select medium wavelength ultraviolet or white light illumination to view fluorescent gels or visible blots.

The UV-B (312nm) intensity of the TVD-1000R can be varied. This flexibility in irradiance control helps ensure the longest sample preparation time, while minimising actual UV damage to the sample.

The Bi-O-Vision has two sample platforms, each with a filter area of 8 x 8" (20 x 20 cm). The UV side is lit by five 8-watt UV-B tubes and delivers nanogram sensitivity for detecting ethidium bromide-stained DNA or RNA. The white light side has three 8-watt fluorescent tubes that ensure excellent illumination for viewing Coomassie blue-stained protein gels, methylene blue-stained DNA gels and autoradiograms.
