How Clean is Your Surface? Contact Angles as a Measure of Cleanliness

Originally Aired:

Date: February 28, 2023


Is your surface clean? Is surface cleanliness critical to your fabrication or manufacturing process?

In this webinar, our Attension Product Manager Dr. Vincent Ovalle will demonstrate how contact angle measurements can be used as an invaluable tool to determine the cleanliness of a surface. Compared to qualitative tests that are material and user-dependent or more complex methods that are expensive and time-consuming, measuring the contact angle of a liquid droplet on a surface can provide immediate, quantitative insight into its cleanliness.

Utilizing an optical tensiometer with advanced droplet creation/placement and automated drop fitting analysis, contact angle measurements are an accurate and reproducible method to quantify just how clean is your surface.
