The Bi-O-Vision transilluminators from Spectroline (Westbury, NY) produce both 312 nm ultraviolet and white light. Two adjacent workstations each have a 20 × 20 cm filter area: the UV side is lit by five 8 W UV-B tubes and delivers nanogram sensitivity for detecting ethidium bromide-stained DNA or RNA, while the white light side has three 8 W fluorescent tubes for viewing Coomassie blue-stained protein gels, methylene blue-stained DNA gels and autoradiograms.
“Two-in-One” Transilluminator Provides Top Quality Photodocumentation
Westbury, New York — 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 life science researchers to select the exact ultraviolet or white light illumination needed to photodocument samples with a single piece of equipment.
The UV-B (312nm) intensity of the Bi-O-Vision can be varied without preset stops, from 6,000 to 3,000 µW/cm², and the white light output can be adjusted from 2,000 to 1,000 foot-candles (186 to 93 lux). This flexibility in irradiance control ensures the longest sample preparation time, so researchers do not have to worry about UV damage to samples.
The Bi-O-Vision has two adjacent workstations, 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.
