The KLU-V 2100 from ATTO LABWARE is a highly advanced Double Beam UV-VIS Spectrophotometer designed for precise and reliable analytical measurements across a wide wavelength range of 190 to 1100 nm. With a grating of 1200 lines/mm, it ensures high spectral resolution and accuracy for diverse scientific and industrial applications.


It features an auto wavelength setting, LCD display, and supports multiple photometric methods like Absorbance (A), Transmittance (T), and Concentration (C). Equipped with Deuterium & Tungsten lamps, and a Silicon Photodiode detector, it offers high sensitivity and minimal stray light for superior measurement performance.


Thanks to its USB & parallel port connectivity, data can be easily printed or transferred to a PC using the included UV Analyst Software. It also supports automatic lamp switching, multi-wavelength measurements, and up to 9 wavelengths and 8 sample measurements simultaneously, ensuring efficient analysis.
