Trade name
Evolution™ 220 UV-Visible Spectrophotometer
Technical description

The UV-Vis spectrophotometer is a device designed to measure the absorption of electromagnetic radiation in the visible and near and medium ultraviolet range in liquid samples. Spectrophotometric measurements are used in quantitative analysis (determination of concentrations of various organic and inorganic substances), qualitative analysis, physicochemical research (e.g. for kinetic research), as well as for structural research. The programmable temperature adapter with a Peltier cell, being an additional equipment of the spectrometer, extends the spectrometer's capabilities by performing measurements at precisely set temperatures in the range of 0-110oC, as well as examining temperature dependencies. Equipped with attachment for reflectance measurements.

Research capabilities

The UV-Vis spectrophotometer allows you to make quantitative, kinetic and point measurements as well as perform spectra in the entire spectral range (190-1100nm).

Thanks to the temperature shift, it is possible to measure spectra at different temperatures in the range of 0-110oC.

Possibility of testing solid samples (thin layers) with the reflection method.
