Attension Theta Flow tensiometer for surface research

Saturday, 01 May, 2021 | Supplied by: ATA Scientific Pty Ltd


The Theta Flow from Attension is a contact angle meter that is designed to integrate a high level of automation to simplify measurements and increase accuracy. With its high-end camera, image enhancement technology and built-in sensors, the product builds on the Theta Flex, which was a recipient of the Red Dot award in 2020 for its neat design and ease of use.

The tensiometer offers three main benefits that are not believed to be available on other systems. Camera autofocus, automatic surface mapping and automatically generated results are some of the automation features that should help simplify measurements and improve accuracy. A high-resolution 5 MP camera combined with DropletPlus technology enables image enhancements.

Fully integrated tilt and level sensors help keep track of the surrounding environment and, together with temperature and relative humidity sensors, are designed to ensure traceable data. The touch display meanwhile assists users by simplifying the measurement set-up; everything from filling the liquids to changing samples can be done easily from the instrument in seconds.

Defining baselines is a critical aspect of measuring contact angles which requires the droplet in focus and the substrate well exposed. When substrates have large depth or the surface is not uniform, the substrate surface is often darkened and the contact area obscured. The Theta Flow’s autofocus function, together with the DropletPlus image enhancer algorithm, is designed to improve the chances of correct baseline placement, particularly for challenging samples.

High-end features make the Theta Flow suitable for surface measurements such as static contact angle, dynamic contact angle, surface free energy, surface and interfacial tension, roughness-corrected contact angle and 3D surface roughness, and interfacial dilatational rheology.
