Drop Shape Analyzer

Precision 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 DSA30M Drop Shape Analyzer enables drops in the picoliter range to be accurately positioned and analyzed. The resulting contact angle is exactly the information you need for optimizing wetting and coating processes on very small surfaces.
