The automated premium solution for wetting and adhesion analysis of solids and liquids
The Expert version of the DSA100 Drop Shape Analyzer system solution enables solids and liquids in wetting and coating processes to be analyzed comprehensively. The high degree of automation with easy programmable procedures provides for user-independent contact angle and surface tension results, which is ideal for the use in quality control. However, the DSA100E is also frequently used in R&D due to its versatility in controlling thermal conditions, its dosing solution with four (optional: up to eight) test liquids, and its scientific tools for analyzing the solid/liquid contact.
