In this video, we show you how to use contact angle meter model SL200KS which provides you with automatic direct syringe
pump, drop transferring stage and rotating stage for measurement of roll off angle. We show you a measurement of contact angle for
fresh lotus leaf (super-hydrophobic surface) and measurement of roll off angle for the same lotus leaf. Contact angle for fresh lotus leaf is about 160° and roll off angle is about 10°. Visit http://www.uskino.com to find more information about our contact angle meter.
