Equipment

The Chair of Electrochemistry has comprehensive, modern equipment at its disposal. Analytical balances, drying cabinets, water baths, thermostats etc. are available for basic sample preparation.

Furthermore, special equipment is available for spectro-electrochemical experiments: Glovebox; actively damped optical bench; voltage/current supply and measuring devices; temperature-controlled and rotatable measuring cells.

In particular, the following analytical instruments are available for spectro-electrochemical investigations:
