Wettability instrument offers accurate and easy characterisation of solids and liquids

Dyne Testing, an Intertronics brand, offers Attension Theta Flex from Biolin Scientific, a contact angle meter developed for reliable and repeatable analysis of wettability and adhesion in research, development, quality and industrial applications. The device comes with OneAttension software, a comprehensive suite that comprises all contact angle measurement modes, an easy-to-use interface and free, unlimited licenses and upgrades.

The device is a premium optical tensiometer created for advanced wettability research and provides the flexibility needed for diverse or demanding research requirements. It can measure surface and interfacial tension between fluids, contact angles between solids and liquids, and analyse surface free energy values – providing all measurements in one instrument. The functional, modern, and award-winning design is modular, which you can configure for your needs and expand when needed. Its high-end imaging, together with sophisticated analysis algorithms, detect and analyse the contact angle and surface free energy precisely.

The included OneAttension software supplies pre-defined recipes that ensure easy and fast measurement setup. Its free and unlimited licenses permit 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 motorised sample stage and motorised 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 allow 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 200C.

“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.
