The Standard configuration of the DSA100 Drop Shape Analyzer system solution 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, which is equipped with a robust housing, is well-suited 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.

The DSA100: Why we call it premium
Comprehensive and versatile wetting and adhesion analysis for almost all surfaces and tasks: see what’s possible with the DSA100.
Controlled drop dosing and easy sample positioning
With the DSA100S, 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 DSA100S is also equipped with three manual axes for moving the sample to the required positions quickly and precisely without having to touch the sample.
Reliable drop shape analysis thanks to high imaging quality
The DSA100S 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.
Protective housing and time-saving setup
The robust housing of the DSA100S protects sensitive components such as the camera and also minimizes the troublesome effect of vibration.
Adjusting the viewing angle, which is often necessary when measuring the contact angle, is particularly easy since the position of the drop in the image does not change during this step. As a result, the otherwise necessary tracking of the sample height is eliminated. This is possible thanks to a special optical arrangement, which also creates space for large samples.
Software procedures for accurate time control
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.
