Labmate Single Beam UV/Visible Spectrophotometer LMUS-A304
Labmate Single Beam UV/Visible Spectrophotometer LMUS-A304 operates across a wavelength range of 190 nm to 1100 nm with a spectral bandwidth of 2 nm. It features an automatic wavelength setting and replaceable pre-aligned tungsten and deuterium lamps for consistent and reliable performance. 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 pharmaceuticals, environmental analysis, chemical industries, quality control, and research laboratories.
