The Drop Shape Analyzer

The Krüss DSA 100s Drop Shape Analyzer in Cleanroom A-1

The Krüss DSA 100S Drop Shape Analyzer will analyze the shape of a drop of liquid on a surface, or suspended from a needle, in order to calculate the contact angle, or the surface tension, respectively. It is mostly used to determine the contact angle of water as a measure of the hydrophobicity/hydrophilicity of the sample surface.

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) and method used; usually around ±0.5°. Using several measurement points is recommended.
Process parameters Available liquids
  • Syringe 1: Water (H2O)
  • Syringe 2: Diiodo-methane (CH2I2)
  • Manual dispense is also possible
Sample requirements Substrate material allowed
  • In principle all materials allowed in cleanroom
Substrate size
  • Up to 6" wafers. In order to measure, a few mm2 of flat surface is required.
Batch size
  • One sample at a time
