Electrochemical test cell ElyFlow
In contrast to the usual test cells, Gaskatel test cell ElyFlow is made of PTFE, because
glass is a poor material. Firstly, it breaks quickly. Secondly, it is chemically stable only to
a limited extent because silicates dissolve. This is a particular problem with aggressive
solutions such as alkalis.
But also for light sensitive electrolytes glass is an insufficient material.
In very poorly conductive electrolytes, the conductive silicate layers cause an uneven field
line distribution.
Like the Gaskatel test cells FlexCell, ElyFlow is also characterised by high mechanical
stability and high chemical resistance. The plastics have no influence on the field line
distribution.
In ElyFlow, as in the FlexCell measuring cells, the electrolyte chamber has been designed
in a tubular shape.
ElyFlow is also designed so that you can pump your electrolyte from a storage vessel
through the measuring cell with the help of a diaphragm pump.
This allows longer measurement times. The flow rate should be less than 0.1 l/min.
In addition, the electrolyte in the storage vessel can be continuously monitored during the
measurement: Temperature, conductivity, pH value, analysis of reaction products.
Use a heatable storage vessel when measuring at higher temperatures.
