T7/T7S UV-Vis

T7:      UV-Vis Spectrometer        

T7S:    UV-Vis Spectrometer        

T7/T7S is a high performance split beam scanning spectrophotometer available with variable spectral bandwidth, which is innovative in terms of instrument application, mechanical and optical design. Electronic control and software enable this while maintaining features that are well established and accepted through the industry.


T7/T7S is able to carry out photometric measurements, spectrum scans, quantitative determinations and DNA/Protein analysis. When interfaced to a PC using the UV-Win software, many more features are available including three-dimensional spectrum, kinetic measurements, method and data storage, exportation of data in multiple formats and GLP administration features.

Key Features

◆ High performance variable spectral bandwidth


◆ Wavelength accuracy +/- 0.3nm


◆ Supplied with a motorized 8 cell changer and pre-aligned Tungsten and Deuterium lamps


◆ Additional accessories for multi application


◆ High degree of automation requiring minimal key depressions to start analysis
