Main Features

Electronic ballast and cutting-edge construction offers:

  • Increased ultraviolet output and intensity

  • No light flicker

  • Wider intensity range with variable selection (select models)

  • Fast lamp start up

  • Universal power supply

  • Reduced electrical consumption

  • Longer tube life

  • Lighter weight

  • Improved gel visualization and gel documentation

Transilluminator Features:

  • High performance 25-watt UV tubes for high fluorescence and sensitivity on stained gels

  • Stainless steel cover frame provide an easy clean surface and reduces cross contamination of samples

  • Uniform, brilliant back-lit fluorescence illumination is enhanced with UVP's unique background uniformity screen and UVG long-life filter

  • Uniformity screen is available on units with midrange or longwave UV

  • The transilluminator's powerful cooling fan maintains a low filter surface temperature to prevent sample damage and maintains a constant UV intensity

  • The removable and adjustable protective UV blocking cover is included with each transilluminator

  • Transilluminators carry a two-year warranty

WARNING: Transilluminators are powerful sources of ultraviolet radiation which can cause serious damage to unprotected eyes and skin. Read the ultraviolet Caution Information before operating any transilluminators.



Select models offer single intensity other models include variable intensity. Refer to the part numbers tab for information.

Variable intensity settings - High/Medium/Low

High setting allows for UV excitation of fluorophores on gels for routine photography. Medium is excellent for viewing and quick single-band excision. Low setting allows for positioning and preparation of gels, excising multiple bands, and focusing for photography.
