Description
Spectrophotometer Shimadzu UV-1900i
The UV-1900i is a double-beam UV-Vis spectrophotometer using Shimadzu’s original LO-RAY-LIGH™ diffraction grating technology. In addition to its high optical performance, the UV-1900i features high resolutions, low stray light, high reproducibility, and an ultra-fast scan function. It also has an easy-to-use interface on a color touch-screen display. The UV-1900i designed to meet the needs of both high performance and usability.
