contact angle meter model SL200KB made by USA KINO. Visithttp://www.uskino.com to find more information about our contact angle meter or surface tensiometer for measurement of contact angle or surface tension or interface tension.In this video, we show you how to use this contact angle meter and how to measure contact angle of powder with super-hydrophobic surface. You can find out it is harder to transfer drop to super-hydrophobic surface. We use needle with OD 2mm and use Young-Laplace equation fitting method (4th generation) to measure contact angle for this case.
