D2 Lamp for Waters Alliance 2996 PDA/DAD is manufactured under the brand name of Cyberlab. Deuterium lamps use the stable arc discharge mainly in the ultraviolet range. It functions as a discharge light source. These lamps are preferred over light-hydrogen arc lamps. The D2 lamp has a tungsten filament and an anode within a nickel box. The lamp functions as a light source by creating an arc from the filament to the anode. The deuterium is excited to a higher energy by this process. The spectrum for D2 lamp extends from 122 nm to 900 nm. D2 lamps are used for high pressure liquid chromatography and UV spectroscopy purposes.Product name: D2 Lamp for Waters Alliance 2996 PDA/DADSpecification: Equivalent to P/N WAT052586/WAT057760
