The top view contact angle analyzer - TVA100 is the only instrument in the world that uses the top reflection method to measure the liquid-solid contact angle from above. This innovative measurement method is very suitable for liquid droplets inside concave surfaces that cannot be analyzed using traditional side views.
measuring method
Measurement of contact angle grooves using the top-down distance method. The special contact angle measurement method uses all common models to measure the contact angle with several testing liquids. The surface free energy achieves excellent resolution within a small contact angle range, which can be used as a standalone instrument or as a measurement module for DSA100, DSA30, or DSA25. It can be used as a special equipment for measuring inside the orifice plate
