The droplet shape analyzer - DSA25 is a reliable contact angle measuring instrument that is simple and easy to use. From simple wettability testing to accurate determination of surface free energy, DSA25 can provide flexible choices for analyzing surface wetting and adhesion, with stable results. Its fast and manual operation makes DSA25 particularly suitable for testing needs that require temporary changes in sample type.
measuring method
Measure the contact angle between liquid and solid based on all existing models, calculate the surface free energy static contact angle, measure the liquid liquid interface tension (using the hanging drop method) at the forward and backward angles, and measure the inclination angle at specific humidity within the temperature control range of -30 to 400 ° C
