Watch the story of the Liquid Needle, our new, revolutionary dosing technique for contact angle measurement. The novel dosing method is a fast and exactly reproducible way of placing drops on solid surfaces with minimum kinetic energy using a very thin jet of liquid instead of a solid needle. Our developers reveal the process of its creation from the very first idea to the finished device. Our team of scientists talks about how they validated the new method and published the impressive results in a scientific paper. In this they had proved that, in spite of the much higher speed compared to the classical solid needle, the contact angles are identical on each of the tested surfaces of a wide range of materials.
