Attension® Product Options
Attension Theta Optical Tensiometers are able to perform a complete range of automated measurements, which makes them a highly versatile instrument in research, industrial, and QC laboratories. Measurements include: static contact angle with the sessile drop, captive bubble and meniscus methods, dynamic contact angle with the tilted drop and needle-in drop methods, surface free energy, surface/interfacial tension with the pendant drop and reverse pendant drop methods, surface roughness correction with integrated optical profilometry, and interfacial dilatational rheology with the pulsating drop method.
The best-in-class instrument for measuring contact angle, surface tension, surface free energy, dynamic contact angle, and much more. Includes features that remove user bias and streamlines processing with key instrument settings, improving data quality.
The Theta Flex is an award-winning, advanced, and versatile optical tensiometer for highly accurate measurements of static and dynamic contact angle, roughness-corrected contact angle, surface free energy, surface and interfacial tension, and interfacial rheology.
The Theta Lite is a compact, entry-level and accurate optical tensiometer for static and dynamic contact angle, surface free energy and much more. Ideal for basic research and quality control but boasts the same precision and all-inclusive software as our more advanced Theta Series systems.
