The Drop Shape Analyzer

The Krüss DSA 100S Drop Shape Analyzer will analyze the shape a drop of liquid on a surface, or suspended from a needle, in order to calculate the contact angle, or the surface tension, respectively.

An overview of the performance of the Drop Shape Analyzer

Purpose Imaging and analysis of of the shape of the interface between liquid and air
  • Measurement of contact angle between sample surface and liquid
  • Measurement of surface tension of liquid
Performance Measurement accuracy
  • Highly dependent on analysis conditions (image quality and fitting model), usually around ±0.5°
Process parameters Available liquids
  • Syringe 1: Water (H2O)
  • Syringe 2: Diiodo-methane (I2CH2)
  • Syringe 3: Benzyl alcohol (C6H5CH2OH)
  • Syringe 4: Available
Sample requirements Substrate material allowed
  • In principle all materials
Substrate size
  • Up to 6" wafers. In order to measure a few square mm's of flat surface is required.
Batch size
  • One sample at a time
