Schematic representation of a UV-Vis spectroscopy setup. It illustrates how light from a combined source of ultraviolet (UV) and visible (Vis) light is directed onto a sample. The light that passes ...

YourWater Testing Needs, All in One Spectrophotometer The DR 6000 has the most pre-programmed testing methods, including high-speed wavelength scanning across the UV and Visible Spectrum.

But state-of-the-art ultraviolet and visible (UV-vis) spectrophotometry, which measures electronic transitions of a wide range of molecules as they absorb light, was cumbersome and expensive. In July ...
