Precise lathering
The foam reproduction method of the SITA automatic foam analyzer has been proven to accurately distinguish various sample formulations and reproducible test sequences; the device is suitable for multiple applications;
The SITA separation tower uses a standard honeycomb rotor for stirring.
Adjustable rotor parameters: stirring times, rotation speed, stirring time, starting speed, stirring direction
The test tank is made of glass, which has less impact on foam formation.
The rotor is integrated into the test tank and can be removed together

Measuring foam---using non-contact optical measurement technology
Foam surface scanning device: Use structured light measurement method to determine the three-dimensional morphology of the foam surface to determine the total volume of the foam
Foam interface scanning device: Determine foam structure and liquid volume by using a better mobile camera system that illuminates and observes the test tank at an angle higher than the critical angle Î, achieving total internal reflection function
Automatically collect the total amount of liquid and foam through the foam surface scanning device; automatically collect the remaining total amount of liquid and total foam through the foam interface scanning device
All measurements are performed in the same measuring tank and connected to the thermal cycle
Record the foam structure throughout the foam height in the test tank
Analyze foam and understand foaming behavior
Use the SITA-FoamLab operating software in the laboratory for simple and convenient evaluation of measurement data
The test process and results are completely transparently presented to users through intuitive and visual graphics.
During foam formation, analyze slope (foaming speed) and final foam volume (foaming capacity)
Analyze the decay and subsidence process of bubbles
Analyze bubble size and shape in foam structures:
(1) Comprehensive description of foam and foaming behavior
(2) By further determining other parameters, such as: half-life and foam density
(3) By individually evaluating height-related foam structural parameters such as average bubble size or roundness index
(4) By tracking changes in foam structure over time
(5) Different measurement sequences are clearly displayed, allowing for flexible data comparison.
(6) Easily export data and measurement results for archiving and backup
