The Perkin Elmer Lambda 20 is a double-beam UV/Vis Spectrometer designed for routine quantitative and qualitative analysis in the ultraviolet and visible spectral ranges. It typically operates within a wavelength range of 190-1100 nm, with a spectral bandwidth of 1nm or 2nm. This instrument is widely used for concentration measurements, kinetics studies, and spectral scanning of samples in solution across various scientific disciplines.
