Manual measurements with Du Noüy ring and Wilhelmy plate methods
The Attension range of contact angle meters and precision tensiometers from Biolin Scientific provide outstanding ease of use for liquid and solid surface characterization in research and industrial processes. Measurements include surface roughness, wettability, surface free energy, contact angle and interfacial rheology. Analytes that can be characterized include superhydrophobic surfaces, polymers, coatings, surfactants, devices, and nanocomposite material. The product range consists of optical and force tensiometers for research and development. Attension products also provide solutions for high-throughput development, quality control and process control and are widely used in the chemical, pharmaceutical, electronics, food, energy, paper and packing industries.
Attension Theta Flex is the contact angle meter that enables all measurements in one instrument. It is designed for reliable and repeatable measurements of wettability and adhesion, even in the most demanding industrial and research applications.Sigma 700/701 are the ultimate Attension force tensiometers enabling full automation and optimal ease of use even for the most demanding industrial and research applications.
