Measure the wettability of microscopic surfaces by almost any liquid – with the DSA30M Flexible Liquid from KRÜSS.

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 Drop Shape Analyzer DSA30M Flexible Liquid dispenses picoliter drops of the liquids and determines the contact angle as a relevant measured variable when wetting and coating processes on tiny surfaces are to be optimized.

Whether a user needs to determine the surface free energy with several liquids or investigate the wetting of a whole range of formulations, the DSA30M Flexible Liquid is perfectly equipped to do so:

  • Drops down to a volume of 10 picoliters on a sample
  • Uncomplicated disposable cartridge system ensures quick changes between several liquids
  • No cleaning or maintenance is required as the dosing tip is part of the cartridge
  • Thanks to the high-quality microscope lens and the bright, homogeneous illumination, reliable measurement results from image analysis are guaranteed
  • With the high-speed camera, even rapidly evaporating or absorbed droplets can be examined smoothly
