Hamaker 2 is a freely available software for the prediction of interparticle forces and the resulting stability of suspensions.

For more information, please see Colloidal Stability or the user manual included in the distribution.

Key features:

  • Interparticle dispersion forces: Non retarded Hamaker, Vincent, Gregory, effective Hamaker
  • Electrostatic interparticle forces: Hogg-Healy-Fürstenau, Linear superposition approximation
  • Steric interparticle forces: Close to hard wall
  • Extensible by user programmes plug-ins
  • 2D and 3D plotting against any model parameter
  • Easy to use graphical user interface
  • Real time plotting of interaction potentials
  • Cross-platform: Windows, Mac, Linux
  • Estimation of barrier required for stability period
