UV lamp 11W Ultraviolet lamp, that emits ultraviolet light in the wavelength range of 350 to 400 nm (UVA) and maximally at 370 nm. The lamp connects directly to the mains and has an on/ off button. Note: The ultraviolet light from this lamp presents no health risk to the eyes or bare skin. Item no. 287100 Ultraviolet bulb Black light 125 W lamp with outer casing of Wood's glass. Can be used to produce fluorescence in optical laundry detergents, investigating foodstuffs, mineralogy, and fluorescent inks and paints. The lamp emits ultraviolet light in the wave length range of 310 to 410 nm with a maximum at 365 nm (mostly UVA, but with a small amount of UVB). The lamp is fitted with an E27 socket, but must NOT be connected directly to the mains supply. Fit the bulb into 287000 Socket and power it via 284050 Control transformer for spectrum lamps. Item no. 286000 287115 UV lamp, battery-powered Diffuse ultraviolet lamp with a wavelength of around 365 nm. Item no. 287110 Zinc sulphide screen Phosphorescent plate that continues emitting light for some time after having been illuminated. This effect depends on the light source emitting some ultraviolet in addition to visible light, which means that the screen can be used to detect UV light. Includes Ø 10 mm mounting post. Dimensions: 110 x 105 mm Item no. 307500 Phosphorescent plate Similar to 307500, but unmounted. Dimensions: 70 x 95 mm Item no. 307510 287140 UV torch This flashlight is suitable for studying fluorescence; for example, our 287140 UV beads rapidly change colour when illuminated. Emits long wave UV light (350-400 nm). Item no. 287115 UV torch, student Emits long wave UV light (395-400 nm) Uses 3 x AAA batteries, sold separately. Item no. 287120 UV beads UV beads which are white-ish in artificial light but become coloured under UV light. Approx. 100 beads. Item no. 287145 UVA accessory set UVA accessory set containing an ordinary glass plate, a fluorescent plate, a phosphorescent plate, a UVA filter, UVA plastic film and ordinary plastic film. Instructions included. Item no. 287210 Fluorescent plate, 70x95 mm Plate that fluoresces when illuminated by UV light. Can be used to demonstrate fluorescent chemicals and which materials block UV light. Dimensions: 70 x 95 mm Item no. 307600 42 42
