The standard version of our Drop Shape Analyzer is a special version of our DSA100 system solution for measuring the contact angle and the surface free energy of a solid. It provides all the technical advantages of the DSA100 system with regard to optics and sample size. We have put together the additional, flexible components of the DSA100S especially for quality assurance and the scientific investigation of wetting and coating processes.
Manual axes for the three spatial directions enable the required measuring position to be adjusted accurately and without contact, even for larger samples. Our liquid dosing unit is software-controlled and enables the drop volume and the dosing feed to be precisely adjusted. This enables the measuring conditions for the contact angle to be accurately reproduced. Measuring the advancing and receding angle averages out local inhomogeneities and provides reliable data for assessing the roughness of the solid.
After dosing, the software can start the measurement automatically and record raw data immediately. A precise value for the surface free energy can be quickly determined from contact angle data of several test liquids thanks to the rapid exchange of dosing syringes and the programmable, semi-automatic measuring sequences.
The DSA100S and the software can be upgraded to any other system configuration at any time. This enables the degree of automation and the standardization of the measuring sequence to be increased as required. You also have access to the comprehensive range of accessories for the DSA100 for adapting the measuring conditions to specific processes.
