About SITA FoamTester for Foam Analysis

The SITA FoamTester will easily analyse the characteristics of surfactant-containing liquids giving precise results with automated measuring sequences.  The instrument uses innovative optical measurement methods to determine foam characteristics such as foam volume, stability, drainage and foam structure.

With innovative optical scanning technologies, the FoamTester enables a comprehensive analysis of liquid foams.  An important tool for R&D and QA in any industry (e.g. cosmetics, detergents, surfactants & lubricants).

Scope of Delivery:

The system consists of a removable measuring vessel with stirring unit, an integrated sample reservoir with magnetic stirrer, a cleaning system with external water source, an automatic optical measuring system, touch display for operation directly at the device and the SITA-FoamLab software.

 

Features & Benefits

SITA FoamTester

  • Out of the box operation with pre-configured experiments and automated procedures
  • Fast contact-free and high-resolution optical scan of the foam structure with structured light.
  • Reliable and continuous detection of the foam-liquid interface even with opaque liquids.
  • Fast and high-resolution measurement of the foam structure for the entire foam level, analysis of the different bubble sizes and other parameters.
  • Fully automated measuring process including sample conditioning and cleaning.
  • Individually programmable sequences for generating and analysing foam.
  • Reproducible foam generation with reliable stirring method and flexible test parameters.
  • Individually programmable sequences for generating and analysing foam as well as easy operation with pre-set or customised experiments.
