Semi-automatic wettability analysis with high dosing precision
The Standard version of the DSA25 Drop Shape Analyzer measures the static or dynamic contact angle with high precision and can also be used to determine the surface free energy by carrying out measurements with several liquids. The instrument provides rapid results for the wettability of a surface, for example for checking the quality of cleaned, pretreated, or coated samples.
