difference of Wilhelmy Plate method from four company

In this video, we show you the difference of Wilhelmy Plate method from four company - Ateension (Biolin), Kruss, Kyowa and KINO. All videos from other company are from the video published at Youtube. KINO's method used Young-Laplace equation corrected method and will correct buoyance and contact angle. So, we named this method as 3rd generation Wilhelmy Plate method. It can be used to measure surface tension between liquid-gas and interface tension between liquid-fluid system, and it can be also used to measure dynamic contact angle based on Wilhelmy Plate method. But, we suggest it is prefer choice to select optical contact angle meter such as contact angle goniometer SL200K series to measure contact angle
