ElyFlow PTFE Electrochemical Test Cell (GAS-83400-v03)
OVERVIEW
ElyFlow PTFE is a three-electrode electrochemical test cell designed for electrolyte circulation. It accommodates flat samples such as metal sheets, foils and gas-diffusion electrodes. The fixed distances between the working, counter and reference electrodes provide defined geometric conditions for comparable measurements.
The cell incorporates a laterally positioned Haber-Luggin capillary and supports gas supply to the working electrode. External vessels and pumping systems can be used to increase the available electrolyte volume and support long-duration measurements. The PTFE construction provides chemical resistance across a pH range of -2 to 16 when the appropriate counter electrode is selected.
