Surface Free Energy Calculation

JikanCompany May 3, 2020May 9, 2020 Technical Note No Comments

Jikan CAG-20 contact angle goniometers measure the surface free energy of solids (solid surface tension) from contact angle measurements. The algorithm used in the software (Jikan Assistant) requires the user to measure the contact angle of at least one test

Automatic contact point detection

JikanCompany May 3, 2020May 9, 2020 Technical Note No Comments

Only few contact angle goniometers provide the back to front tilt of the camera (Fig. 1 a). This feature enables the user to perfectly see the contact point (Fig. 1 b). It also enables the software (Jikan Assistant) to automatically pick the contact points.
