Metrohm Autolab

SPELEC1050 is an instrument for performing spectroelectrochemical measurements. It combines in only one box a Lightsource, a Bipotentiostat/Galvanostat and a Spectrometer (VIS-NIR wavelength range: 350-1050 nm) and includes a dedicated spectroelectrochemical software that allows optical and electrochemical experiments synchronization.
