KRÜSS releases the Foam Tester, a new instrument for testing liquids with respect to their foam formation and stability behavior, focusing on quality control for foam prevention and inhibition.
Foam Tester Measures Stability of Foam
For quality control in formulations, it is necessary to exactly determine the foaming behavior of the liquids and foam-inhibiting additives involved. The Foam Tester carries out the task in an exactly repeatable manner. The results provide significant information for the foaming capacity of liquids and the decay speed of the resulting foam.
The Foam Tester provides for standardized
foam formation by electronically controlled gas flow and for objective result reading thanks to precise, electronic foam height detection. The measurement is carried out automatically and user-independently using easily adaptable automation programs.
By recording the total height of foam inside the measuring column and the liquid height beneath the foam, data are related to the absolute amount of foam and also give conclusive results for the liquid content and flow-out speed.
Tester Captures Even Fast Decay Processes
For unstable foams, the Foam Tester records the decay curve with a particularly high data rate. The automated cycles can reveal whether the foam level decays fast enough or rises from measurement to measurement. To adapt the conditions to the real process, measurements can be carried out temperature-controlled at up to 90°C and also with externally connected gases, such as carbon dioxide.
The Foam Tester allows preparing the measurement in a few easy steps. The measuring cylinder is placed in the instrument with a single movement using the plug-in unit. The flexible system, which simply uses paper filters to provide the pores for foaming up, enables all components to be cleaned quickly. It also allows one sample to be prepared while another measurement is running in order to save time. The clear data management with the instrument’s ADVANCE software ensures gapless documentation of raw data and end results.
