Model Selection Guide
EC-UV1 — Single-chamber
A compact single-chamber design with an ITO working electrode and sapphire optical window. Recommended for conventional in situ UV–Vis spectroelectrochemical measurements. Select this model when direct monitoring of potential-dependent spectral changes is required.

EC-UV2 — Two-chamber, Membrane-separated
An H-type two-chamber design with a replaceable membrane and gas access to the working compartment. Recommended for in situ UV–Vis studies requiring electrode-compartment separation. Select this model when membrane separation or controlled gas introduction is required.

Published Application Example
Potential-Dependent In Situ UV–Vis Monitoring of Ir-Based OER Catalysts
Shen et al. used a custom transmission-type in situ UV–Vis electrochemical cell compatible with a Shimadzu UV-2600 to investigate the oxidation-state evolution of CeO₂–IrO₂ and IrO₂ during oxygen evolution. The catalyst was deposited on a transparent FTO working electrode in the optical path. Potential-dependent and time-resolved UV–Vis measurements revealed sequential Ir redox transitions and correlated absorbance changes with electrochemical charge accumulation.
