Attension Theta optical tensiometer

Click2Contact

The Attension Theta is a versatile optical tensiometer or contact angle meter used to characterise surfaces and interfaces between gas, liquid and solid phases. It provides measurements of static and dynamic contact angle, 3D surface roughness, surface free energy, surface and interfacial tension, and interfacial rheology. The optical tensiometer is used in research, development and quality control in a variety of industries such as chemicals, pharmaceuticals, electronics, foods, energy, paper and packaging.

Driven by the growing popularity of the technique, a series of upgrades have been developed for the Attension Theta optical tensiometer. One of these upgrades is a dual dispensing system which utilises two disposable tip dispensers. This allows the user to quickly determine surface free energy (SFE), which provides valuable information about the surface chemistry. The automatic disposable tip dispenser makes cleaning easy while also enabling the drop volume to be dispensed precisely by calculating the droplet volume from the live image.

A further upgrade includes the product’s camera, which offers advanced imaging to capture fast wetting phenomena up to 3009 fps and precise drop shape analyses with 1984 x 1264 pixel resolution.

The unit can be combined with a 3D topography module that can measure both contact angle and surface roughness of the sample in a single measurement and calculate the contact angle without the effect of the roughness.
