SITA FoamTester

Analyse foam parameters, control the effects of surface-active surfactants

The new generation of SITA FoamTester
20 years of experience meets innovative foam testing

With SITA FoamTester, the foam properties of solutions containing surface-active agents can be analysed precisely and reproducibly with automatic measurement procedures.

  • Fully automatic foam analysis
  • Reproducible foam formation
  • Measurement of foam and liquid volume
  • Analysis of foam structure
  • Recording of drainage
  • Automated self-cleaning system


Create foam


Differentiation of various sample formulations and reproducible test sequences using an application-oriented foam creation method.

  • Established SITA standardized stirring disc
  • Low impact of the vessel's glass on foam formation
  • Removable measuring vessel with stirring unit
  • Variable stirring parameters: speed, duration, acceleration, direction, interval

Process & Technical Specification

Recording of key foam properties

  • Volume measurement
  • Contactless determination of total volume using structured light method
  • Determination of remaining liquid volume using total reflection
  • Foam structure
  • High-resolution imaging of foam structure across a wide range of
    foam heights using total reflection

Practical evaluation of measurement data using SITA-FoamLab software remotely from the office computer

Full transparency in the measurement process and results through intuitive visualization
Complex data presented in significant numerical values (foam properties)

  • Analysis of foam breakdown and drainage
  • Analysis of bubble sizes and shapes in foam structure
  • Easy comparison and visualization of multiple measurement and reference results
  • Easy export of data and results for documentation
  • By determining foaming potential and half-life
  • By evaluating individual height-dependent foam structure parameters
  • By tracking time-dependent changes in foam structure
