Contact angle measuring instrument DSA30 series

R&Dbenchtop

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. Applications • - Quality assurance of activation processes such as plasma treatment, flame treatment, or corona treatment • - Analyzing wettability of plastics, glass, ceramics, wood, paper, or metal • - Analyzing the effectiveness of hydrophobic coatings and other coatings • - Analyzing coating liquids and adhesives and assessing their adhesion • - Assessing long-term stability of coatings • - Analyzing (super-) hydrophobic and self-cleaning surfaces • - Analyzing homogeneity of cleanliness and wettability and measuring differences between coated/uncoated or treated/untreated areas • - Wetting analysis at controlled temperature and/or humidity Measuring methods • - Contact angle of a drop on a solid surface • - Contact angles of two drops dosed in parallel • - Automated position-dependent contact angle measurement and evaluation • - Contact angle using a gas bubble beneath a solid surface in a liquid • - Roll-off behavior and advancing/receding contact angle of a drop on a tilted surface • - Surface free energy of a solid using contact angle data • - Calculating adhesion-related scientific parameters for the interfacial contact
