Thermo Scientific Evolution 60 UV-Vis Spectrophotometer with VISIONlite Software, PC and Single-Position Cell Holder

The Thermo Scientific Evolution 60 UV-Vis spectrophotometer is a split-beam instrument for absorbance measurements, wavelength scans, quantitative analysis and biochemical assays in life sciences laboratories.

This unit includes VISIONlite software, a PC with monitor, keyboard and mouse, and a single-position cell holder. The PC and VISIONlite software provide computer-based instrument control and data acquisition. The single-position cell holder accommodates one sample cell.

The used instrument has been tested and is in good condition. Test scans were performed through VISIONlite software, and data acquisition was observed in remote mode. A holmium spectrum was recorded with an external Thermo Scientific UV Validator kit. The UV Validator kit is used for testing only and is not included.
