Our advanced Contact Angle Measuring Instrument coupled with the Drop Shape Analysis software can provide our clients with the following possibilities:
- Determination of contact angles of single drops of test liquids on a solid surface (tangent, height-width, and YOUNG-LAPLACE (sessile drop fitting) methods)
- Measurement of advancing and receding contact angles by volume control of sample drop
- Determination of surface free energy of solid samples by means of various methods (FOWKES, OWENS/WENDT/RABEL/KAELBLE, SCHULTZ, WU, ZISMAN, and acid -base methods) mentioned in the literature
- Determination of surface and interfacial tension of liquids with the drop shape analysis (pendant drop method)
Practical Applications
- Surface cleanliness determination
- Cleaning methods evaluation
- Wettability - Wetting behaviour study
- Adhesion study
- Printability evaluation
- Surface treatment and coatings evaluation
