Double Beam Spectrophotometer - UV-Vis Analyzer - 190-1100 nm - 8-inch Touchscreen

The Master Science Double Beam Spectrophotometer combines a Czerny-Turner double-beam optical system with a large 8-inch color touchscreen, giving laboratories a practical instrument for qualitative scans and quantitative measurements across 190 to 1100 nm.

Zero and full-scale adjustment and wavelength setting are automatic, and internal memory keeps results, scans, regression curves and correction data ready after each start-up.
