Drop Shape Analyzer – DSA100

The universal, high-quality instrument for analyzing wetting and coating processes.

DSA100 is our high-quality system solution for almost all tasks in the analysis of wetting and adhesion on solid surfaces. From the basic unit for precise measurement of the contact angle to the fully automatic expert instrument for serial measurement of surface free energy, we have the right DSA100 for your special requirements. We exactly match the individual, flexible and reliable components to your surfaces and processes.

We have developed all components of the DSA100 to provide solution-oriented support in the investigation and optimization of wetting and adhesion behavior. With up to three axes for sample positioning, the sample is moved quickly and reproducibly to the measuring positions. Measurement of the contact angle with up to 8 liquids ensures maximum accuracy when determining the surface free energy. Precisely controlled tempering and humidity chambers help to provide a realistic modeling of the process conditions. Our special sample tables optimize the investigation of wafers and ultrahydrophobic surfaces. High-tech solutions for optical components enable a time-saving, automatic image setup, and measurement of extremely fast wetting processes. They also allow measurements to be made on microscopically small samples.
