| • | 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 | |

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 | ||
