Double Beam UV-Vis Spectrophotometer LUS-B40 a bench top device with 190 nm to 1100 nm wavelength range, and offers spectral bandwidth of 0.5/1/2/4 nm. Equipped with 16 mm thick rigid aluminium board as optical base, which highly ensures stability and reliability. Features dual optical path, dual beam optical system, dual detector, uses high performance imported prism grating, Tungsten Lamp & Deuterium Lamp as light source, and Imported silicon photodiode as detector with stronger stability, reliability, delivers results that are more accurate. Designed with 10 inch TFT Touch colored screen, can work on powerful software as well, and it performs functions like Photometric measurement, Quantitative measurement, Kinetics, Spectrum scan, DNA/Protein test, Multi-wavelength test etc. Three operation modes are available; they are Host, Computer and Mobile phone (App). This advance, high quality spectrophotometer supports USB data transfer and storage system.
