The Accuris™ E3000 UV Transilluminator features a space-saving design, with a width of only 10.5 inches, to fit perfectly in any busy laboratory. However, the 16 x 19 cm UV viewing surface is sized to accommodate large gels or multiple smaller gels.
This ultraviolet transilluminator comes with array of high intensity UV bulbs coupled with an optimized filter provides even illumination across the viewing surface and allows detection of small sample quantities. The dual intensity switch can be used to lower the UV intensity to 50% to reduce DNA damage during long exposure times, or switch to high intensity (100%) for viewing weak fluorescent signals or for photo documentation.
The acrylic UV blocking cover allows safe viewing of samples and has two friction hinges on the front edge to allow angling of the cover for gel access. The cover can be positioned to 90° (straight up) to fit a gel imaging hood, such as the Accuris SmartDoc™ imaging enclosure.

Use Cases for Ultraviolet Transilluminators
Ultraviolet transilluminator have multiple use cases, including but not limited to:
-
Gel electrophoresis analysis - UV transilluminators are commonly used in molecular biology labs for viewing DNA or RNA that has been separated by gel electrophoresis.
-
Visualization of proteins - proteomics, ultraviolet transilluminators are often used to visualize proteins that have been separated in a gel and stained with a UV-sensitive dye.
-
Sample preparation - they assist in the preparation of samples for further analysis of experiments. For example, when DNA fragments need to be cut out from a gel after electrophoresis, a transilluminator helps locate the fragment for extraction.
-
Photodocumentation - these devices are often connected to cameras for capturing images of the gels. This is important for recording and analyzing data, sharing results, and for maintaining records in lab notebooks.
-
Forensic analysis - in forensic science, ultraviolet transilluminators can be used to visualize certain substances and fluids (like blood, fibers, or fingerprints) that fluoresce under UV light, aiding in crime scene investigations.
-
Clinical diagnostics - they can be used in clinical diagnostics for visualizing different types of samples that have been tagged with fluorescent markers.
-
Microbial studies - microbial studies involve UV transilluminators to observe the growth and behavior of microbes that have been dyed with UV-sensitive stains.
-
Educational purposes - they are also used in educational settings, like university labs, to teach students about molecular biology techniques.
What are the benefits of UV transilluminators?
Some of the main benefits of UV transilluminators include:
-
Improved visualization - they play a crucial role in analyzing gel electrophoresis results for the visualization of nucleic acids (DNA and RNA).
-
Increased sensitivity - because UV transilluminators are sensitive, they can detect small amounts of biomolecules, which is critical for experiments with limited sample quantities.
-
Non-destructive analysis - since the visualization process tends to be non-destructive, allowing for further analysis of the samples after viewing.
-
Efficiency - efficiency is among the biggest benefits of UV transilluminators, as they are able to provide quick and easy detection of samples, which simplifies lab workflows.
Reduced risk of contamination - since the process is non-invasive, there is a lower risk of sample contamination compared to methods that require physical contact with the samples.
1. What is the price of a UV transilluminator?
The price of a UV transilluminator can vary widely, typically ranging from $200 to over $2000. This variation depends on factors like wavelength options, size, brand, and additional features like camera integration or safety enhancements. For specific pricing, it's best to consult manufacturers or scientific equipment suppliers.
2. What is the wavelength of UV transilluminators?
UV transilluminators usually operate at wavelengths of 254 nm, 312 nm, or 365 nm. The 254 nm wavelength is used for DNA cross-linking, 312 nm for routine DNA or RNA viewing, and 365 nm for less DNA damage during longer exposure. The choice depends on the specific application and sensitivity required.
3. What is the intensity and uniformity of the UV light?
The intensity and uniformity of UV light in transilluminators vary by model. High-quality units provide intense, uniform UV illumination, essential for consistent and accurate gel visualization. Lower-end models might have less uniformity, affecting the analysis precision of DNA or protein gels.
4. Are UV transilluminators compatible with gel documentation systems?
Many UV transilluminators are designed to be compatible with gel documentation systems. This compatibility allows for easy integration with cameras and software for gel imaging and analysis. However, compatibility depends on the specific models of both the transilluminator and the documentation system.
5. What is the durability and lifespan of UV bulbs in UV transilluminators?
The durability and lifespan of UV bulbs in transilluminators vary, but typically they last for about 300 to 500 hours of use. High-quality bulbs can have longer lifespans. Regular use and maintenance can impact longevity, and it's important to follow manufacturer guidelines for optimal performance.
