Drop Shape Analyzer
DSA100M
The premium solution for wettability analysis of microscopically small surfaces
The wettability of very small surfaces can have a great influence on product quality, e.g. for contact points on circuit boards or in microfluidics. The DSA100M Drop Shape Analyzer is the premium solution for accurately positioning and analyzing drops in the picoliter range. The resulting contact angle is exactly the information you need for optimizing wetting and coating processes on very small surfaces.

Perfectly equipped for microdrop analysis
The available dosing units for 20 or 60 picoliter minimum volume dispense microscopically small drops of test liquid onto the sample. The fine positioning of the dosing unit and the sample allows precise placement of the drops. This step is particularly easy with the included observation optics which shows the sample in a second camera image.
Thanks to the high-quality microscopic lens and powerful illumination, the DSA100M has high image quality that enables reliable measurement results from image analysis. With the help of the instrument’s high-speed camera, even ultra-small, rapidly evaporating drops can be easily analyzed.
Working with two test liquids also enables the surface free energy to be calculated. This result provides important information for the adhesion, e.g. of fiber coatings.
