Labmate Single Beam UV/Visible Spectrophotometer LMUS-A308
Labmate Single Beam UV/Visible Spectrophotometer LMUS-A308 operates over a wavelength range of 190 nm to 1100 nm with a spectral bandwidth of 4 nm. It features automatic wavelength and blank setting, along with replaceable pre-aligned tungsten and deuterium lamps for reliable performance and easy maintenance. Equipped with a silicon photodiode detector and graphic LCD display, it provides accurate, low-noise measurements with minimal stray light. The sample compartment accommodates 5–100 mm path-length cuvettes, making it ideal for laboratory, pharmaceutical, and environmental applications.
