Semi-auto Precision Contact Angle Goniometer
Used for evaluating solid surface treatment, analyzing plasma cleaning effects, assessing surface cleanliness, studying solid-liquid adhesion characteristics, liquid formulation design, and characterizing surface printability. It is also applied in the analysis of surface modification and the study of wettability on glass, plastics, and metal surfaces.
Scope of Application
Used for evaluating solid surface treatment, analyzing plasma cleaning effects, assessing surface cleanliness, studying solid-liquid adhesion characteristics, liquid formulation design, and characterizing surface printability. It is also applied in the analysis of surface modification and the study of wettability on glass, plastics, and metal surfaces. Contact angle measurement has become an essential tool for surface property evaluation in industries such as mobile phone manufacturing, glass production, surface treatment, materials research, chemical engineering, semiconductor fabrication, coatings and inks, electronic circuits, textiles and fibers, as well as medical and biological fields.
