There are many choices for a blue light transilluminator and there is a reason this system is one of our best sellers. The UltraSlim blue LED transilluminator price and build quality makes it a great value! Available with an optional white light pad, the UltraSlim is a very compact, ultra thin transilluminator suitable for imaging gels up to 12 cm x 10 cm and stained with SYBR Safe, MaestroSafe stain, Gel Green, and other "safe" stains.
108 high intensity, side illuminated 470 nm blue LED bulbs offer outstanding signal to noise ratio.
The UltraSlim blue LED transilluminator has a variable, adjustable position amber viewing screen for superb viewing and easy access to gels for band extraction.
Easy visualization of DNA gels stained with:
- SYBR Safe
- Ethidium Bromide (EtBr)
- Gel Green
- UltraPower DNA Safe Dye
- Midori Green
Will I see my bands? Yes, you will!

This is a commonly asked question and concern from anyone looking at purchasing a blue light transilluminator online. The picture above was captured at a customer lab in Cambridge, MA. It is an image of a DNA gel stained with SYBR Safe placed on an UltraBright blue light transilluminator (the larger version of the UltraSlim).
As you can see from the reflection on the screen, this image was captured with the lights on in the room. In fact, the system was placed directly under a ceiling light. The UltraSlim blue LED transilluminator is ultra bright!

Imaging Hood included with every system
An imaging hood is included as standard with ever system. The imaging hood provides a simple and affordable way to capture images of your gels directly onto a mobile device.

Optional White Light Panel makes the UltraSlim Blue LED transilluminator even more versatile!
Do you work with protein gels? A white light panel is now available with the UltraSlim. This enables scientists to view and image nucleic acid and protein gels with a visible stain such as Coomassie blue or Silver Stain. The white light panel can be used external to the system or can be placed in the UltraSlim Blue LED Illuminator.
Safe to use and does not damage DNA
Despite the increased interest in "safe/non-toxic" DNA gel stains such as SYBR Safe or GelGreen, many labs still use UV transilluminators on the bench. Exposure to UV can cause sunburns to skin or eyes. Additionally, UV can accidentally crosslink and damage your DNA. As the UltraSlim uses blue light, there is no risk of sunburn or damage to DNA. Simply put, this is a safer system to use on the bench.
