Cole-Parmer Blue Light Transilluminator; 115V

Description

Cole-Parmer's blue light transilluminator is used for visualizing nucleic acids following gel electrophoresis. It employs blue light LEDs with a peak emission wavelength of 465 nm. This illumination source is considered safer for DNA and RNA samples than traditional ultraviolet light, as it reduces photodamage that can impair downstream applications such as cloning or PCR. The unit operates on 115V AC power, making it compatible with standard electrical outlets in regions using this voltage. In practice, gels are stained with dyes that fluoresce under blue light, causing nucleic acid bands to become visible for observation, documentation, or excision from the gel.
