About Teclis

Built by scientists who understand interfaces — not just how to measure them, but why the measurements matter.

TECLIS Scientific grew out of academic research in interfacial science in the early 1990s. The founders were working at the forefront of the field and shared a common frustration: the instruments available at the time could not capture what they actually needed to see. Equilibrium measurements were straightforward enough, but the dynamic behavior that governed real-world performance — adsorption kinetics, interfacial rheology, the viscoelastic response of a surfactant-laden interface — required something that did not yet exist.

So they built it.

The original TRACKER pendant drop tensiometer, introduced in 1995, was designed from the beginning to do more than measure a static surface tension value. It captured the time-dependent evolution of the interface — how quickly surfactants adsorbed to a freshly created surface, how the interface responded to controlled oscillations, and what those responses revealed about the mechanical properties of the interfacial film.

The FOAMSCAN foam analyzer followed, applying the same philosophy to foam science: replacing subjective visual observation with simultaneous, quantitative measurement of foam volume, drainage, liquid fraction, and bubble size distribution.

Three decades later, that founding principle has not changed. Every instrument TECLIS builds is designed to give scientists access to the complete picture — not just what the interface looks like at equilibrium, but how it behaves, how it responds, and how it evolves over the timescales and conditions that matter to their application.

TECLIS instruments are used by researchers and formulation scientists around the world — in consumer products, food science, life sciences, oil and gas, and academic research. Our installed base is not the largest in the industry, and that is by design. These are instruments built for scientists who need more from their measurements than conventional tensiometers and foam testers can provide.

TECLIS Scientific headquarters and research laboratories are located near Lyon, France, where instrument development, manufacturing, and application research continue side by side. TECLIS America serves customers throughout the United States and Canada from Boulder, Colorado.

If you are working with interfaces or foams and want to understand more than what conventional measurements can tell you, we would welcome the conversation.
