Complex measurements. Clear solutions.

Advancing Electrochemistry since 1997

Welcome to Gaskatel

We would like to introduce ourselves and show you what makes Gaskatel a trusted partner in electrochemistry.

Based in Kassel, Germany, we are a small and highly specialized company serving industrial customers, research institutes, and universities around the world. Supported by our international sales network, we provide products and services to customers across a wide range of electrochemical applications.

Ordering is simple and convenient. Customers can place orders at any time via email or through our user-friendly online shop.

Service Makes the Difference

What our customers value most is the expertise and personal support provided by our team.

Whether you have a question about a product, need assistance with a measurement, or are looking for the right solution for your application, our experienced specialists are ready to help.

Because we develop our products ourselves, we understand them in detail and can provide practical, knowledgeable support by phone or email.

Innovation Through Experience

Our expertise not only benefits our customers through technical support and consulting - it also drives the continuous development of our products. We work closely with users and regularly incorporate customer feedback into new and improved solutions.

More Than Products

If you would like to benefit from our expertise even further, we also offer testing and measurement services. From conducting experiments to interpreting results, we support you in obtaining reliable and meaningful data.

We look forward to helping you find the right solution for your electrochemical challenges.

Our Mission: Understanding Electrochemistry

At Gaskatel, understanding electrochemistry is more than our mission - it is the foundation of everything we do.

For over 25 years, we have combined expertise in physics, chemistry and engineering to explore, measure and better understand electrochemical processes.

This knowledge is built into every product we develop, from reference electrodes and pH electrodes to advanced measuring cells, helping researchers and engineers generate reliable results with confidence.

Setting the global standard in electrochemical referencing.

Our hydrogen reference electrode is the only commercially available electrode worldwide that complies with IUPAC recommendations. Based on the original concept developed by Nobel Prize winner Walter Nernst, it delivers the highest level of scientific accuracy and traceability.

Unlike conventional glass electrodes, our hydrogen pH electrode measures pH directly through the hydrogen electrode reaction, eliminating the need for a glass membrane as the sensing element.

Measure what matters: corrosion current density and corrosion rate.

Our corrosion test cell measures the true current density at the exposed sample surface, enabling accurate determination of corrosion rates. It provides direct insight into corrosion current density and corrosion rate, delivering meaningful data on real corrosion processes.

From Research to Practice

Gaskatel GmbH was founded in 1997 by members of Prof. Winsel’s working group at the University of Kassel.
Since then, our interdisciplinary team of physicists, chemists, engineers and laboratory specialists has been developing, manufacturing and distributing innovative products for electrochemical applications.
We use analytical measurements to better understand our customers’ challenges and turn this knowledge into practical, reliable solutions.

Electrochemical measurements can be complex. Our goal is to make them simpler, more reliable, and more accessible.

But why is electrochemistry so complex?

In electrochemistry, the chemical redox reactions are divided between two electrodes connected by an electrolyte and an electrical conductor.
Although the reactions are spatially separated, they are not independent of each other. This prevents the system from being arbitrarily simplified, as is common in physics.

One way to achieve this is to introduce a third measuring electrode - the so-called reference electrode. This was assigned to the hydrogen electrode by the IUPAC in 1953. This is referred to as a measurement with a reference value.
This is very common, for example, with temperature. Here, the zero point of 0°C is defined as the state of frozen water. Another example is the water level at a distance above sea level.

Using a reference electrode and a potentiostat that sets the desired reaction at the anode or cathode, the electrochemical reactions can then be investigated quite precisely.
But even here, the system is not completely independent. To decouple this, special measuring cells are required.

Gaskatel has developed such a test cell.

Nevertheless, electrochemistry remains challenging because the charge carrier concentration and charge carrier mobility of the electrolyte vary enormously, by about 16 orders of magnitude.
