FlexCell® PTFE – electrochemical test cell made of PTFE

Voltammetric cell especially for gas diffusion electrodes, corrosion measurements and battery electrodes

This test cell works for all flat materials! Measurement error sources like IR drop, curvature of field lines or boundary effects caused by the sealing are minimized.
Haber-Luggin-capillary drilled on the side with fixed distance to the working electrode.
For plane working electrodes ∅ 3 cm.
Gas feed of the working electrode: therefore well applicable for gas diffusion electrodes.
Auxiliary analyte compartment for tests with separated anolyte and catholyte. Provides the possibility of tests with membrane or separator.
Applicable from pH -2 to pH 16
