Theta

• Modularity and extensive accessories enable you to choose the level of automation and the advanced functionalities that you need for your particular application. Modularity also makes the system upgradable and secures long-term needs.
• Unique innovative features and options, such as the possibility to combine contact angle measurement with 3D topographical measurements, and to get roughness corrected contact angles as a result. This makes it possible to understand the influence of surface roughness and chemical modification separately on wetting and adhesion properties.
• OneAttension software for all measurement options—modern and user-friendly software that is based on over 20 years of experience and close co-operation with our customers. The software platform enables easy implementation of customized features and functionality for special demands.
• Attension’s extensive service and application support team will help you get the best from your instrument. Pre-studies can be conducted in an AttensionLab to assess the feasibility of your research, test samples for verification, and demonstrate the suitability of Attension instruments to your research.

Product details

Theta is able to perform a complete range of automated measurements, which makes it 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 sessile drop methods, surface free energy, surface/interfacial tension with the pendant drop and reverse pendant drop methods, 3D surface roughness with the Fringe projection phase shifting method, andinterfacial dilatational rheology with the pulsating drop method.

Theta enables you to choose the level of automation and the advanced functionalities that you need for your applications. It also a high degree of modularity and an extensive range of accessories that allow you to upgrade or change the instrument as your needs evolve.

Attension optical tensiometers use a monochromatic cold LED light source and a smooth lighting integration sphere to minimize sample evaporation. Image quality is guaranteed with a high-resolution digital camera and a high-speed data transfer between the computer and the instrument.

The system comes with OneAttension control software for analysis of drop shapes. It uses for example, the Young-Laplace equation as a reference method and can fit the entire drop profile. It complies with the promise of performance and simplicity:

• Fully automatic measurements avoid user dependent variation and saves time.
• Select ready-made experiment recipes or create custom programs for quick and repeatable operations.
• Automatic base line detection and drop shape fitting
• Contact angle on curved surfaces (circular or near-circular)
• Flexible and programmable frame per second rate recorded by the camera

OneAttension is an all-inclusive software that enables immediate access to all measurement capabilities with no need to purchase and install separate software modules. It features an intuitive user interface, live analysis, configurable user groups and accounts and a preset liquid database. Any datapoint or groups of datapoints can be selected, transformed, plotted and analyzed. In-depth analysis takes seconds and data can be easily exported.
