What our customers say


Our tensiometers are used at MIT to study contact angles and interfacial energy. A researcher at MIT commented, “The reproducibility of the measurements acquired is excellent even with the lowest surface energy values and the tensiometers are quite flexible with regards to sample size. The software is also very useful and the customer support for the products is excellent.”

MIT is one of the most prestigious universities in the world focusing on scientific and technological research.

A customer from NASA said he “has enjoyed working with the Attension team as well as the Attension products during novel research projects.”
