NEWS & UPDATES

NEW Liquid Dispensers for Attension Theta Flow, Flex & Lite

We are thrilled to share the news about this exciting enhancement to the full range of Attension Theta Optical Tensiometers! With an all-new design that allows the use of up to 4 different liquids, these advanced new dispensers enable more precise dispensing of low surface tension liquids, small volume drops, as well as high density and high viscosity liquids. 

From high volume QA/QC measurements to complex surface energy characterization, the new dispensers will allow users of Theta Flow, Flex, and Lite instruments to boost the accuracy and repeatability of their measurements.

Technique Note: Detecting Residual Solvent in Polymer Films with Contact Angle Measurements

When fabricating thin polymeric layers, organic solvents are used to dissolve the polymer to reach a low enough viscosity or a specific phase for processing. Ideally, the solvent is then removed amid manufacturing or with post-processing conditions. However, the need and effectiveness of post-processing to remove residual solvents are not always known or verified.

This new White Paper explores one technique that can detect the presence of residual solvents rapidly and easily and can be readily coupled with polymer manufacturing—measuring water contact angle using optical tensiometry.

How Surface Wettability Affects Biomaterials and Biomedical Devices 

Wettability is an important material property that affects a material’s response to its surrounding environment. For biomedical devices and biomaterials, wettability determines how the material will interact with proteins, cells, …

Watch On Demand

In this recent webinar, Dr. Emily Lentz highlighted the importance of wettability characterization for predicting how biomaterials and medical devices will interact with proteins, cells, and bacteria in a biological environment.

Overcoming Surface Roughness in Contact Angle Measurements

When using contact angle measurements to analyze the wettability of a surface, certain assumptions are often made about the sample: the surface is unreactive, rigid, insoluble, chemically homogenous, and smooth. …

Watch On Demand

Whether you are measuring contact angle to analyze medical device biocompatibility, printing on paper, structural integrity in additive manufacturing, or characterizing surfaces after abrasive processing, it is well established that surface roughness enhances the existing wetting behavior and influence on adhesion.
