Fully automatic contact angle tester

Fully automatic contact angle testerIt is a professional instrument for measuring the contact angle between liquids and solid materials, with the core purpose of characterizing the wetting performance of liquids on the surface of solid materials. Its workflow is to obtain droplet images through an optical imaging system, use computer software to fit the contour of the droplet image using mathematical models, and then obtain contact angle or surface tension data. Surface energy calculation and wettability analysis can be carried out to provide accurate basis for material surface performance evaluation.

Scope of application

Fully automatic contact angle testerWidely used in multiple industries, including mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textile fibers, medical biology, etc., it has become an important instrument for evaluating surface performance.

The specific testing and analysis functions that can be implemented are as follows:

a. Analyze the wetting behavior of liquids on solid surfaces, such as spreading, permeation, and absorption, and measure the static contact angle using the seat drop method;

b. Measure the advance angle, retreat angle, contact angle hysteresis, rolling angle, and dynamic contact angle of materials on solid surfaces;

c. Conduct continuous real-time research on absorbent materials and record the process, generate contact angle variation curves over time, and conduct analysis;

d. Measurement of contact angle for special materials such as powders, curved surfaces, superhydrophobic/superhydrophilic samples, etc;

e. Using the attachment droplet method to test the contact angle of materials immersed in liquid;

f. Using the suspended droplet method to measure the interfacial tension, polarity, and dispersion components of various liquids;

g. Calculate the surface free energy of the solid and analyze its polar dispersion component;

h. Analyze the adhesion work of liquids on solid surfaces and evaluate the uniformity and cleanliness of solid surfaces.

(Note: Some testing functions require the purchase of specialized accessories to be completed)
