Analysing foam parameters, Controlling surfactant effects
The long-time successful SITA foam tester R-2000 was the first fully automated foam tester with a reproducible foam generation.More than 15 years of experience in foam testing led to a next generation testing device, the new SITA FoamTester.

• Innovative optical measuring method • Fully automated foam analysis • Precise reproducible foaming • Measuring foam and liquid volume • Analysing foam structure • Recording drainage |
Product Description
The SITA FoamTester analyses the characteristics of surfactant-containing liquids easy, fast and precise with automated measuring sequences. The measuring device uses innovative optical measuring methods to determine foam characteristics such as foam volume, stability, drainage as well as foam structure.
The SITA FoamTester offers:
| • | Fast contact-free and high-resolution optical scan of the foam surface 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 characteristic values |
| • | Fully-automated measuring process including sample conditioning and cleaning |
| • | Reproducible foam generation with reliable SITA stirring method and flexible test parameters |
| • | Individually programmable sequences for generating and analysing foam as well as easy operation with pre-set or costumised experiments |
The foam testing 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 and a touch display for operation directly at the device as well as the software SITA-FoamLab.
