Contact Angle Meter Summy

Contact Angle refers to the tangent line of the gas-liquid interface at the intersection point of gas, liquid and solid. This tangent line has an Angle between the liquid and the solid-liquid boundary. The measurement of Contact Angle is the main method of surface performance detection nowadays.

Standard contact Angle measurement instrument is to use the principle of optical imaging, image contour analysis way to measure the surface contact Angle, wettability, interfacial tension of table, surface energy, such as performance, equipment cost-effective, comprehensive functions, and can meet the demand of conventional measurement, has been widely used in many colleges and universities institutes and enterprises.


Contact Angle measuring instrument is widely used in various industries, in the mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical and chemical industry, semiconductor manufacturing, paint and ink, electronic circuits, textile fiber, medical biological and other fields, contact Angle measurement has become an important instrument to evaluate the surface performance.

(some test functions need to be completed by purchasing special accessories)

1. Wetting behaviors of liquid on solid surface, such as spreading, infiltration and absorption, etc., static contact Angle was measured by droplet method;

2. Measurement of forward Angle, backward Angle, contact Angle lag, rolling Angle and dynamic contact Angle of materials on solid surface;

3. Continuous real-time research and process recording of absorption materials, and curve analysis of contact Angle changes with time;

4. Measurement of contact Angle of various special materials, such as powder, curved surface, superhydrophobic/superhydrophilic samples;

5. Test the contact Angle of the material immersed in the liquid by adhesive drop method;

6. Measurement of interfacial tension, polarity and dispersion components of various liquid surface by droplet method;

7. Calculate the Surface free energy and analyze its polar dispersion component;

8. Analyze the adherent work of liquid on solid surface to evaluate the uniformity and cleanliness of solid surface.
