in this video, we show you how to measure contact angle of flour using contact angle meter SL200K. From video, we can find out that first contact angle of flour is higher and after water adsorbed into flour, contact angle is changed. By CAST3.0, you can easy to capture total process of adsorption and measure live contact angle . And you can re-calculate the result with differenet method such as Young-Laplace equation fitting method at CAST3.0.
