Shimadzu Spectrophotometer UV-1800

Product Details

Designed in accordance with the governing Japanese and European Pharmacopoeia, the new UV-1800 UV-VIS spectrophotometer achieves a resolution of 1 nm, the highest in its class, in a compact design. Offering an array of user-friendly features, the UV-1800 can be used either as a stand-alone instrument or as a PC-controlled instrument.

High resolution – 1 nm

Featuring the highest resolution in its class*, the UV-1800 easily satisfies the standards of wavelength resolution demanded by the European Pharmacopoeia.
Additionally, using a spectroscope with a Czerny-Turner mounting results in a compact, bright optical system. Stray light, wavelength repeatability and baseline stability have also been advanced to meet user requirements.
*As of March 2007, according to Shimadzu research.

Space-saving design

Only 450 mm wide, the UV-1800 is one of the most compact instruments in its class, allowing installation in tight spaces. In comparison to the UV-1700, the setting space has decreased by about 15%, and the width has narrowed by about 20%.

User friendly

USB memory can be connected directly to the UV-1800. Users can now analyze data on a PC using UVProbe software. In addition, data for spectra and time-course curves can be displayed and saved with commercial spreadsheet software. Printing is possible to printers that support PCL control codes. Using UVProbe software, provided as standard, makes it possible to control the UV-1800 with a PC. (A USB cable is required for connection to the PC.)
