Contact Angle Profile Analysis Tensiometer PAT1P-CA


09

The contact angle is the angle formed by a liquid at the three phase contact line where a liquid, gas and solid intersect. The shape of the drop is controlled by the three forces of interfacial tension shown in the figure. The contact angle is a quantitative measure of the wetting of a surface by a liquid. It can as well be used as a control measure in surface treatment and cleanliness.
