WESTBURY, N.Y., Jan. 7, 2011 — The Spectroline Bi-O-Vision Series two-in-one transilluminators manufactured by Spectronics Corp. feature two workstations, producing both 312-nm 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%, enabling life sciences researchers to select the exact ultraviolet or white light illumination needed to photodocument samples with a single piece of equipment.

The UV-B (312 nm) intensity of the Bi-O-Vision can be varied without preset stops, from 6000 to 3000 µW/cm², and the white light output can be adjusted from 2000 to 1000 fc (186 to 93 lx). This flexibility in irradiance control ensures the longest sample preparation time, so researchers do not have to worry about UV damage to samples.

There are two adjacent workstations, each with a filter area of 20 × 20 cm. The UV side is lit by five 8-W UV-B tubes and delivers nanogram sensitivity for detecting ethidium bromide-stained DNA or RNA. The white light side has three 8-W fluorescent tubes that ensure good illumination for viewing Coomassie blue-stained protein gels, methylene blue-stained DNA gels and autoradiograms.
