Top View Analyzer

Wetting measurements in depressions and on concave surfaces

The TVA100B Top View Analyzer is the only instrument in the world to use the top-view distance method for measuring the contact angle of a liquid on a solid from above. The innovative measuring method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the usual side view.

A further strength of the TVA100B lies in the especially high precision in the range of very low contact angles, which makes it an ideal tool for assessing the cleanliness of glass, for example.

Applications

• Measurements in depressions of well plates and other regular and irregular depressions

• Measurement between electronic components on populated circuit boards

• Measurement on optical lenses

• Surface investigations for the interior of tubes and hoses

• Checking of cleaning procedures, especially for glass

Measuring methods

• Contact angle of a drop viewed from the top
• Surface free energy of a solid using contact angle data

Measuring results

• Static contact angle

• Surface free energy
