Versatile automated wetting and adhesion analysis of solids and liquids
The Expert version of the DSA30 Drop Shape Analyzer enables solids and liquids in wetting and coating processes to be analyzed comprehensively. The high degree of automation with easily programmable features provides for user-independent contact angle and surface tension results, which is ideal for the use in quality control. However, the DSA30E is also frequently used in R&D due to its versatility in controlling thermal conditions and its scientific tools for analyzing the solid/liquid contact.
