SITA foam testing is characterised by a high degree of automation and reproducibility. The SITA FoamTester is used to analyse the foam behaviour of surfactant-containing liquids in various areas and applications.
- Influence of formulation and raw materials on foam behaviour in cosmetics
- Investigations of the relationship between the resulting foam structure and user perception
- Influence of contaminations on the foaming in cleaning baths
- Studies on the efficiency and stability of defoamers in cooling lubricants
- Formulation optimization to reduce foam formation during beverage bottling
Create foam
Differentiation of various sample formulations and reproducible test sequences using an application oriented foam creation with proven SITA method
- Established SITA standardised stirring disc
- Minor influence of the vessel glass on foam formation
- Removable measuring vessel with stirring unit
- Variable stirring parameters: speed, duration, acceleration, direction, intervals
Measure foam
Recording the most important foam properties
- Volume Measurement
- Non-contact determination of total volume using structured light method
- Determination of the volume of the remaining liquid by using total reflection
