The Basic configuration of the DSA25 Drop Shape Analyzer is suitable for accurate wetting measurements with a standard test liquid or sample liquid. The instrument is ideal for quick measurements of the static contact angle. It is mainly used for tasks that don’t require a high degree of standardization, i.e. wetting of different formulations of a coating liquid on different samples.
