Foam, Surface, and Interface Science Instrumentation

Teclis makes advanced instruments for measuring the physicochemical properties of interfaces in liquid-liquid, liquid-gas, and solid-liquid systems.

Interfaces are ubiquitous. Interfaces are life. Interfaces are dynamic. Interfaces control the majority of processes and reactions in nature and industry.

Interfaces form when two non-miscible phases come into contact. On a molecular level, interfaces are not perfect lines but regions whose composition changes from one phase to another. They are also dynamic entities that constantly respond to changes in their immediate environment.

Atoms and molecules in these regions have different energies and activity coefficients than those in the bulk phase. The result is that the surfaces or interfaces have a free energy excess, and work is required to change them.

We can understand and characterize these physicochemical properties by measuring their surface and interfacial tension.

Generally speaking, we use the term surface tension when referring to liquid-air interfaces (e.g., foams), and interfacial tension when analyzing liquid-liquid interfaces (e.g., emulsions).

It is important to remember that all surfaces and interfaces are dynamic entities. Therefore, to get a complete picture of how a surface or interface behaves, you need to measure both equilibrium and non-equilibrium states.

At Teclis, we provide you with all the necessary tools to achieve this - to gain a comprehensive understanding of the surface and interfacial properties, enabling you to perform your tasks more effectively and efficiently.

If you need to analyze, understand, or optimize any product, application, process, or research topic involving interfaces (e.g., gas-liquid, liquid-liquid) and surface active substances (i.e., surfactants, lipids, proteins, etc.). In that case, we can offer you robust and versatile analytical platforms.
