Introduction
The UVP Transilluminator offers the researcher uniform and intense sources of ultraviolet light
(radiation) in a compact package. The special design emits high intensity excitation UV wavelength
for back-illumination of transparent fluorescent materials. The 302nm UV back-illumination provides
a highly sensitive method to detect double-stranded nucleic acids that have been labeled with
fluorescent dyes such as ethidium bromide or acridine orange. Single stranded nucleic acids may
be detected, but with a lower excitation wavelength more sensitive for nucleic acid visualization
than the 365nm model.
High Performance UV Transilluminators are fitted with the exclusive 25 watt UV tubes. The
transilluminator is uniquely designed with increased UV intensity and uniformity, instant on
capabilities, no lamp flicker and reduced electrical consumption. Select models include variable
intensity with High, Medium and Low settings. The electronic ballast has a universal voltage
capabilities.
NOTE: Though the manual refers to the midrange UV waveband as 302nm, others refer to this
region as 300nm or 312nm. The spectral output of all these regions is the same.
A Word of Caution: UV Transilluminators are powerful sources of UV radiation that will cause
damage to unprotected eyes and skin. Before operating any unit, be sure all personnel in the area
are properly protected. If not using the transilluminator with an imaging system darkroom, a UV
Blocking Cover should be attached to the transilluminator. Even though this cover blocks the
ultraviolet radiation emitted by the unit, UV Blocking Eyewear should be worn as well.
