Contact Angle | Measurements | Biolin Scientific

Contact angle, θ (theta), is a quantitative measure of wetting of a solid by a liquid. The contact angle is geometrically defined as the angle formed by a liquid at the three-phase boundary where a liquid, gas, and solid intersect. There are three different forces acting on this three-phase contact point between solid, liquid and gas, or in some cases solid, liquid and liquid.
