Cole-Parmer UV Transilluminator, 8W, 254/302/365nm, 20x20cm filter; 115V

Description

This benchtop UV transilluminator from Cole-Parmer is used for visualizing samples after gel electrophoresis. The instrument emits ultraviolet light from an 8-watt source, providing three selectable wavelengths: 254 nm, 302 nm, and 365 nm. The viewing area consists of a 20 by 20 centimeter filter surface, a standard size for accommodating typical agarose gels or membrane blots. It is configured for 115-volt operation, suitable for laboratories in regions with this electrical standard. The availability of multiple UV wavelengths allows the unit to support various laboratory techniques. For instance, 302 nm is commonly used for observing DNA stained with ethidium bromide, while 365 nm may be preferred for applications requiring longer-wave UV to reduce nucleic acid damage. The 254 nm setting can be utilized for other fluorescent visualization protocols. This equipment is a fundamental tool for procedures involving nucleic acid or protein analysis.
