Description

Easy and Repeatable Testing and Monitoring of the Foaming Characteristics of Foaming Liquids
Functionial components of the SITA FoamTester
Benefits of automated foam testing
Autonomous repetition of test runs without intervention by the user
Immediate statements about the reproducibility
Fast and easy screening of test and sample parameters
Convenient sample handling
Automatic sample preconditioning (e.g. temperature, concentration of additives) with external devices
Integrated sample reservoir with magnetic stirrer for running multiple test series
Automated self-cleaning system with external liquid supply (e.g. tap water)
Flexible experimenting
Easy and free creation of experiments at the office PC by drag‘n‘drop using fully parameterisable device tasks and supportive functions (loops and timers)
Creating multiple re-usable templates and exactly repeatable test routines to select and start by a single touch at the device
Instant start with test routines for typical applications pre-defined by SITA

 

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
Variable stirring parameter: speed, duration, acceleration, direction, intervals
Minor influence of the vessel glass on foam formation
Removable measuring vessel with stirring unit

 

 

 

Measure foam

Use of optical, contactless measuring methods
Foam Surface Scanner

Determination of the topography of the foam surface and therefore the total volume using the structured-light method

Foam Interface Scanner

Determination of the foam structure and the liquid level by optimal use of a movable camera system, which illuminates and observes the measuring vessel at an angle Θ above the critical angle for total internal reflection

Automatic acquisition of the total volume (liquid and foam) by the Foam Surface Scanner, of the residual liquid volume by the Foam Interface Scanner and of the foam volume in combination
Analysis of the foam volume of clear and cloudy liquids
Recording of the foam structure over the range of 130 mm x 50 mm
All measurements in the same measuring vessel, connected to the thermal circuit

 

Analyse foam and understand foaming

Convenient evaluation of measuring data with the software SITA-FoamLab in the office
Complete transparency of the measuring progress and the results by intuitive visualisation
Analysis of the slope and the resulting volume during foam formation
Analysis of the foam decay and the drainage
Analysis of bubble sizes and shapes in the foam structure

Analysis of bubble sizes and shapes in the foam structure
Comprehensive characterising of foam and foaming
- By the determination of further parameters such as half-life period and foam density
- By the individual height-dependent evaluation of foam structure parameters such as average bubble size or circularity index
- By tracking time dependent changes in the foam structure
- Flexible comparison by clear display of different measuring sequences
- Easy export of data and results for documentation
