Cole-Parmer UV Transilluminator, 8W, 302/365nm, 21x26cm filter; 115V

Description

A UV transilluminator providing illumination at two specific wavelengths, this Cole-Parmer model emits 302 nm and 365 nm light from an 8-watt source. It omits the 254 nm wavelength found in some other units. The device has a sizable 21 x 26 centimeter filter, offering a generous work surface for gels or blots. It operates on standard 115-volt power. The 302 nm wavelength is widely employed for visualizing DNA fragments stained with intercalating dyes like ethidium bromide following agarose gel electrophoresis. The 365 nm (long-wave UV) setting is useful for techniques where reduced DNA damage is desired or for dyes with excitation maxima at this wavelength. The larger filter dimensions accommodate standard and oversized gels, making this instrument suitable for labs that require a bigger viewing area but do not need the 254 nm UV option.
