Equipment

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

Furthermore, for special measurement preparation of spectro-electrochemical experiments are available: Glovebox; actively damped optical bench; voltage/power supply and measuring instruments; temperature-controlled and rotatable measuring cells.

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