This Model UVL-28 UV lamp is a hand-held 8-watt model equipped with two 365 nm longwave tubes that operate at the same time. It is manufactured with a durable, extruded metal housing and scratch resistant powder paint.
Very lightweight for easy holding or place the lamp in the optional J-138 stand (NC-4983) for hands free operation. Uses 115V A/C current with an 8 ft. cord.
Return Policy: Ultraviolet lamps from Analytik Jena (UVP) have a 20% restocking fee.

RODENT CONTROL... Use the blacklight to detect rodent presence and contamination in warehouses, storerooms, etc. by using an ultraviolet lamp to search out and fluoresce rodent urine. Dry rodent urine glows a blue-white if fresh to a yellow-white if old when exposed to longwave ultraviolet light. Rodent hair glows blue-white and is easily identified on sacks or intermixed with food grains. GEMSTONE and MINERAL INSPECTION UV Light can react with the chemicals of a mineral specimen and cause it to glow, called fluorescence. Color and intensity of the fluorescence can identifty many materials. Some minerals and gemstones will fluoresce under shortwave UV ligh and not fluoresce under longwave. ARSON DETECTION In arson detection, accelerants' fluorescent glow is greater when exposed longer to heat. Their evidence is not always visible as they are absorbed by the fire but UV light can expose them. Volatile hydrocarbons such as gasoline, grease, paints and others fluoresce when exposed to UV, and can be seen as fragments of incendiary devices. Ambient light must be minimized for use of UV light at a fire scene. CRIME SCENE INSPECTION Illegal dumping can be tracked at night using UV light. UV light is used to detect the presence of trace evidence in forensic investigations. Blood, urine, semen and saliva can present visible fluorescence. ARTWORK INSPECTION UV or black light reveals changes on the surface of objects as it causes specific fluorescence in materials depending on composition and age. UV fluorescence can show overpainting or retouching and identify types of stains. One can detect repair in paintings and rugs using UV light, as differences can be seen between the chemical composition of newer inks, paints, and dyes and that of the originals. ADMISSION / ACCESS OR CROWD CONTROL In high-patronage clubs, amusement parks and swimming pools, applying quick drying readmission inks can be read easily by UV light. For beverage control, a portable, small UV light can slip in a pocket. |
