LED470-DF36W
470 nm Blue LED Transilluminator
The LED470-DF36W is a 470 nm blue LED transilluminator designed for safe,
UV-free fluorescence gel imaging.
It provides efficient excitation for blue-light excitable nucleic acid stains, enabling high-contrast DNA/RNA gel observation with dyes such as SYBR Green, SYBR Safe, GelGreen and Midori Green.
This model is suitable for standard UV-free nucleic acid gel imaging workflows where 470 nm blue-light excitation is preferred.

High-Intensity LED Arrangement
The LED470-DF36W uses 24 high-intensity chip-type LEDs arranged on both sides of the luminous surface.
This structure provides strong blue-light excitation while helping keep direct light away from the observer and camera.
Dark-Field Illumination System
The dark-field illumination system directs light from the lower left and right sides of the illuminator.
Because the excitation light does not directly enter the camera or observer, fluorescence can be observed with improved contrast.
Dichroic Filter Effect
The dichroic filter cuts unwanted long-wavelength components from the LED light.
Together with the light-absorbing mat, it helps suppress background glow and improve the visibility of weak fluorescence bands.
Removable Orange Observation Cover
The high-contrast orange sharp-cut cover can be attached and removed easily.
It allows observation and gel cutting while reducing excitation light below 560 nm.
Compatible with Pict LaBox and Bio-Pyramid Mini
Pict LaBox Compatible
The LED470-DF36W can be combined with Pict LaBox for gel observation, cutting and image documentation using a digital camera or CCD camera system.
