Baseline Stability: The Split-beam monitoring ratio system enhances baseline stability.
Excellent Resolution: The big-caliber light path enhances the instrument’s energy, reduces its noise and raises its resolution performance.
Automatic successive measurement: The automatic eight-cell sample holder offers the automatic measurement of eight samples in succession. So it can bring about one-touch measurement of the solution of seven samples and a blank.
User-friendly light source: The light source performs an automatic interchange, selectable within the working range of the light source. The socket deuterium lamps and tungsten lamps facilitate light source replacement, simplify maintenance and reduce operation error.
Convenient Display: The large backlit LCD screen displays both photometric values and spectral curves.
Full use of Computer Technology: Being computer controlled with compatible with Windows XP, & and 8, using the new UVWin 6.0 UV-VIS application software, offering a wide range of uses and applications.
The key components are all adopted from the world famous manufacturer, such as deuterium lamp, silicon photodiode and holographic grating, which ensures the stabilization and credibility of the Instrument for extended life.
Computer System is optional (NOT INCLUDED).
