Cole-Parmer 4-watt UV Lamp with 254nm Wavelength and White Light Tubes, 115VAC

These handheld ultraviolet lamps come in a variety of wavelengths to match your specific UV applications. Choose from one of three UV wavelengths or a combination of UV wavelengths or white light in 4-, 6- or 8-watt configurations. A basic lamp configuration of one UV and one white light tube is ideal for viewing materials in a dimly-lit area. Twin UV models offer two tubes of identical wavelength operating at the same time for added UV intensity. Double UV models with two different tubes allow you to work in any one of two ultraviolet wavelengths. The triple UV model, available only in the 8-watt lamp, allows you the flexibility to easily switch among the three wavelengths (shortwave, midrange, or longwave UV). A selector switch on the back of the lamp makes it simple to switch between light sources on models with multiple wavelengths.The 365 nm longwave UV models are ideal for bacterial identification, specimen staining, gel electrophoresis, chlorination, fluorochemistry, and more. The 302 nm midrange UV models provide an effective tool for gel electrophoresis, gel viewing, and optical lab measurements. The 254 nm shortwave UV models can be used for biochemical testing, mercury detectors, optical alignment, DNA analysis, electrophoresis, and more.A viewing cabinet, for a darkroom environment, can be purchased for the 4- and 8-watt models. An optional lamp stand for hands-free operation is available for all models.
