The Drop Shape Analyzer DSA100 from KRUSS is a high-quality instrument for analyzing wetting and adhesion on solid surfaces.
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. Special sample tables are provided to optimize the investigation of wafers and ultrahydrophobic surfaces.
The particularly uniform LED illumination and high-quality optics ensure high precision when displaying the drop for accurately measuring the contact angle or surface tension. Thanks to the large zoom range, even small drops appear with optimum width in the video image and can therefore be investigated reliably.
