Biolin Scientific Attension Theta Flex optical tensiometer

Monday, 01 April, 2019 | Supplied by: ATA Scientific Pty Ltd


The Attension Theta Flex, from Biolin Scientific, is an all-in-one fully automated contact angle meter designed to support high-end imaging for even the most demanding industrial and research applications.

The modular design and all-inclusive software enable fast and simple operation while sophisticated analysis algorithms allow for repeatable results. Surface properties and interactions can be studied quickly and easily to understand the performance of a product or process. Measurements include static and dynamic contact angle, 3D surface roughness, surface free energy, surface and interfacial tension and interfacial rheology.

Theta Flex can be combined with a wide range of modules and accessories, including the 3D Topography module. By measuring both contact angle and surface roughness of the sample in a single measurement, users can quickly distinguish the effect of roughness on contact angle and surface free energy.

The high-pressure chamber module is designed for wettability research within enhanced oil recovery and enables measurements at pressures up to 400 bars and temperatures up to 200°C. The Pulsating Drop Module oscillates drop volume for interfacial rheology studies while the Picoliter Dispenser delivers picolitre-sized droplets for small sample areas and inkjet applications. For advancing and receding contact angles, a tilting cradle tilts the entire Theta Flex to provide fully automatic dynamic contact angle measurements commonly used as an indicator of surface homogeneity.
