UVP Transilluminators
UVP Biomedical applications (31,380 bytes)


Since 1932 UVP has been involved in developing solutions, particularly for those who work in the ultraviolet portions of the spectrum. Since the 1980's in particular, owing to the dramatic growth of the genetics industries, UVP developed devices that back illuminate subjects in portions of the spectrum including: ultraviolet, visible, or near infrared. These devices are termed Transilluminators.

The Transilluminator is an illuminating platform that incorporates a flat window below which are ultraviolet and or other lamps. These AC powered devices were developed as a backlighting source for DNA gels. However, the Transilluminator can be used for studies of any transparent subject, or to backlight opaque objects so that their perimeter areas between the front and rear of a sample may be more clearly studied. All UV Transilluminator models incorporate an adjustable UV blocking cover, stainless steel frame for easy cleaning, fast start, flicker free lamps, and the UVG long life filter, and uniformity screen to insure consistent illumination across the panel. We are so confident in the reliability and quality control of these systems that all UVP transilluminators sold by Company Seven are accompanied by a two year warranty.

Transilluminators And Their Differences:

Most Transilluminators for gel applications incorporate multiple UV source tubes of 302nm, these may each be 6 watt or higher capacity. But we also offer higher output models, and models in 365nm, or 254nm, or visible light. Some Transilluminator models can provide two or more wavelength sources for example, the 3UV Transilluminators provide the user with the choice of selecting 254, 302, or 365nm. While the 2UV Transilluminators (LM-20 and LM-26) provide the choice of 302 and 365nm sources. The Model Number will usually* include a designation indicating which portion of the spectrum the set is made to provide with 'S' indicating shortwave, 'M' midwave, 'L' longwave. The White Transilluminators bear the prefix 'TW'. The White/UV Transilluminators incorporate a partioned top plate where one side shows white light while the other shows UV; these bear the 'TW' prefix. The 'V' Visi-Blue™ prefix indicates a model specially made to convert UV light for use with 460-470nm excitation samples, SYBR green, SYPRO orange, and GFP stains.

Some Transilluminators feature the capability to vary the brightness of the source, these units (the M-26V for example) will bear a letter 'V' suffix in the model code. This should not be confused with the Visi-Blue Transilluminators that have a 'V' prefix in their model designations.

The Transilluminators also differ in size, we offer compact models with moderate output sources and we also offer larger models. The largest models will bear will bear a letter 'X' in the model code (the FI-26X for example). The available standard production* illumination panel dimensions are listed in the summary below, but note custom sizes can be produced depending on desired quantity, please inquire.

Transilluminator Converter Plates:

These plates are specially designed to convert the ultraviolet radiation produced by a UVP Transilluminator from one wavelength to another or to white light.

  • UV to White Light Plates convert ultraviolet to white light

  • The Visi-Blue™ Converter Plate converts ultraviolet 302nm to 460-470nm UV

  • The UV/UV Converter Plate converts 302nm to 365nm UV

With convenient grab handles at either end of each plate, simply place the appropriately sized plate over the emitting panel to increase the versatility of your UVP Transilluminator. The patent pending phosphored glass is stimulated by ultraviolet radiation from the Transilluminator and this fluoresces emitting the desired resulting light.

UV warning (4,464 bytes) WARNING these Transilluminators are powerful sources of ultraviolet wavelengths, some are invisible to the human eye yet these electromagnetic waves bear high energy and other information. So any structure that absorbs the light can be damaged by this energy; note how sunlight exposure tans the skin while prolonged exposure fades or breaks down materials. The photons of shorter wavelength carry greater energy therefore, these have the greater potential for causing biological damage. These wavelengths can penetrate the eye or skin cells and can produce heating and energy related biological changes that will modify or destroy cellular DNA; this is among the reasons why some UV light sources are used for germicidal (sterilizing) applications.

As amazing as it can be to explore the ultraviolet spectrum, this is not child’s play therefore:

For an overview about working in the UV read our Ultraviolet Spectrum Primer, the illustrated article by Company Seven explaining the ultraviolet (UV) spectrum as it applies to photographing or imaging objects in the UV and about observing fluorescence, phosphorescence, and tenebrescence. The article explains the different portions UV spectrum including UV-A (long wave), UV-B (mid) and UV-C (short wave). We also host numerous articles and lamp users guides at our Notes & Interesting Articles page.
