Attension® Theta Flex from Biolin Scientific is a contact-angle meter designed for reliable and repeatable analysis of wettability and adhesion in research, development, quality, and industrial applications. The Theta Flex comes with OneAttension software, a comprehensive suite that includes all contact-angle measurement modes, an easy-to-use interface, and free, unlimited licenses and upgrades.
The Theta Flex is designed for advanced wettability research and offers the flexibility required for diverse or demanding research needs. It can measure surface and interfacial tension between fluids, contact angles between solids and liquids, and analyze surface free energy values – offering all measurements in one instrument. The functional and modern design is modular, allowing users to configure for their needs and expand when required. Its high-end imaging together with sophisticated analysis algorithms detect and analyze the contact angle and surface free energy precisely.
The included OneAttension software boasts pre-defined recipes that ensure easy and fast measurement setup. Its free and unlimited licenses allow the software to be stored on multiple computers while free upgrades ensure the instrument remains future proof.
“Our Theta Optical Tensiometers combined with OneAttension software offer the most intuitive user interface with a high level of functionality for various industrial applications,” explained Alison Fox, brand manager of Dyne Testing. “The instrument’s modular design means you have choices for dispensing systems, and with an optional motorized sample stage and motorized vertical movement, the Theta Flex can function in a fully automated mode, placing drops in predetermined locations on the substrate and measuring the contact angles.”
Additional modules enable further capabilities, including a 3D topography module for roughness-corrected contact-angle measurements, and a high-pressure chamber for measurements at pressures up to 400 bars and temperatures up to 200°C.
“Understanding of surface energy, contact angle and wettability can be very important in both product design and process development. You can save money, by making the right decisions on substrates and materials, and save time in doing so,” added Fox.
