SPELEC is a tool for spectroelectrochemical measurements. It comprises a spectrometer (UV-VIS wavelength range: 200-900 nm), a bipotentiostat/galvanostat, and a lightsource in one box.
It also comes with specialized spectroelectrochemical software that enables the synchronization of optical and electrochemical studies.
