SHIMADZU UV 1900i Spectro photometer

Shimadzu UV-1900i Spectrophotometer The UV-1900i is a double-beam UV-Vis spectrophotometer using Shimadzu #39;s original LO-RAY-LIGH diffraction grating technology. In addition to its high optical performance, the UV-1900i features high resolution, 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 is designed to meet the needs of both high performance and usability.
