The DSA30 is one of our helpful tools in developing sustainable plastic solutions for the future.
Senior Engineer, Norner
The Standard configuration of the DSA30 Drop Shape Analyzer is designed for the semi-automatic measurement of the static and dynamic contact angle and the scientific assessment of wettability by means of the surface free energy (SFE). The instrument is well-suitable for the reliable quality assurance of surface pre-treatment processes as well as the development and optimization of wetting and coating procedures. Accessories for ultrafast one-click SFE measurement as well as wetting analysis at higher temperatures enhance the spectrum of the instrument.

With the DSA30S, dosing is carried out under software control. Accurately adjustable drop volume and speed ensure repeatable conditions and user-independent results, which is vital for quality control.
Precise measurements of the advancing and receding angle run smoothly thanks to the adjustable dosing dynamics. This measuring mode leads to a statistically significant mean value for the measured sample position.
The DSA30S is also equipped with three manual axes for moving the sample to the required positions quickly and precisely without having to touch the sample.
The DSA30S features a high-resolution camera and a quality zoom lens for accurate display of the drop with optimum size. The high image quality that this achieves leads to a precisely measured contact angle. Combined with the intelligent image evaluation algorithm of the ADVANCE software, drop shape analysis with the instrument provides exact results.
The ADVANCE software can automatically start the measurement process immediately after dosing, thus enabling raw data to be recorded without losing any time. This is particularly important for samples that show a time-dependent wetting behavior.
Equip your instrument with the optional Dosing Hub, our flexible positioning and changing system for up to three combinable dosing units. Together with software-controlled dosing solutions, the system performs automatic and fast surface free energy measurements with up to four liquids, for example. The Dosing Hub also integrates temperature-controlled dosing units and other special solutions.
