The set comprises a glass vessel, an automatic voltage stabilizer, a system for analyzing and recording the output short-circuit current, an added signal system making it possible to record charge density curves (taking into account the sign), an optical system, and a system for stimulating the interface vibrations in the capillary. Typical experimental results for 0.1 M aqueous NaCl and 0.1M-KPF6 in acetone are given.
