Sessile Drop – Measuring Contact Angle

I hope this is helpful for you, if you have any questions on the video, or you’d like some training or advice then don’t hesitate to get in touch

Video Transcript for Sessile Drop-Measuring Contact Angle:

Sessile drop analysis or contact angle measurement entails measuring the angle at which a small drop of liquid contacts a surface. The lower the contact angle the better the wetting of the surface. Contact angle measurements can be employed for dynamic wetting assessments and surface-free energy determination.

Whether you need to understand the wetting ability of a liquid or the wettability of a surface. If you would like to learn more about this technique, please feel welcome to contact us at [email protected]

We provide a fast-turnaround surface tension testing and wetting analysis service for your samples.

We can provide measurements of surface tension and hydrophobicity or hydrophilicity of a surface or liquid as a function of time and/or temperature. On completion of our testing, you will receive a full written report with graphical and numerical results and explanatory notes.

We are an expert measurement lab and any support you may need from us regarding the relevance, interpretation or application of the results we provide is all included in the initial cost of the testing.
