Colloidal interfacial tension measuring instrument

Contact angle calibrator:
Contact angle refers to the tangent line at the intersection of gas, liquid, and solid phases at the gas-liquid interface. This tangent line forms the angle θ between the liquid side and the solid-liquid boundary line. Contact angle measurement is currently the main method for surface performance testing.
It uses the principle of optical imaging to measure the surface contact angle, wetting performance, interfacial tension, surface energy, rolling (sliding angle), forward and backward angle, and hysteresis of the sample through image contour analysis. The equipment adopts a fully automatic liquid inlet device and an automatic overall tilt device, which has comprehensive functions, high cost-effectiveness, and can meet various conventional measurement needs. It has been widely used in many universities, colleges, and enterprises.
