Cole-Parmer UV Transilluminator, 8W, High/Low, 302nm, 20x20cm filter; 115V

Description

This Cole-Parmer transilluminator is configured to emit ultraviolet light at a single wavelength of 302 nm, a common setting for DNA visualization. A notable feature is the ability to operate at high or low intensity, providing user control over the UV output. The unit uses an 8-watt lamp and has a standard 20 x 20 centimeter illuminated filter area. It is designed for 115V operation. The adjustable intensity allows researchers to optimize sample viewing; a higher setting may improve sensitivity for faint bands, while a lower setting can help reduce photodamage to nucleic acids during extended viewing or excision. This model is suited for routine laboratory work where 302 nm illumination is the primary requirement, such as examining ethidium bromide-stained DNA in agarose gels, offering a simplified, single-wavelength design with the added utility of intensity control.
