Our DFA100 instrument for analyzing foams measures the foamability of liquids and the foam stability based on precise measurements of the foam height. With flexibly deployable modules, it also measures the liquid content of the foam or analyses the foam structure with regard to bubble size and distribution. The DFA100 assists in the optimization of foam-forming products or, in the case of unwanted foam formation, helps with specific foam prevention.Reproducible, precise and process-related measurements
A particular strength of our DFA100 is the exceptional reproducibility of foam height measurements thanks to an accurately controlled foaming process with electronic gas flow control. The optical sensor measures the quantity of foam produced and the decay characteristic equally precisely and with high resolution, even with very short-lived foams. As a result, the DFA100 is a reliable instrument for analyzing the whole spectrum from slow to very fast decaying foams. Specific measures for avoiding foam can be taken and the quantity and stability of the foam can be optimized with the help of the results obtained.
We have provided options for producing foam by means of bubbles or by stirring, in order to simulate process conditions and to be able to transfer raw data to large-scale situations. As further options, you can also simulate process temperatures up to 90°C or use externally connected gases such as carbon dioxide.Impressively easy to use
The ease of using the DFA100 when preparing the measurement and when cleaning is of great advantage. The measuring cylinder is simply placed in the instrument using the plug-in unit. The flexible system enables components to be cleaned quickly, and allows one sample to be prepared while another measurement is running. This means more measurements in the same time.
The simple operation of the instrument goes hand-in-hand with the intuitive user guidance of our ADVANCE software. The relevant functions for each particular step are arranged in tiles which display all elements necessary in the context. By avoiding the use of menus and pop-ups, ADVANCE saves any unnecessary clicks and time-consuming searches for hidden elements. Particularly comfortable is the programming of automatic sequences that integrate the software-controlled components of the DFA100 in complete sample analyses with maximum flexibility. Using these automation programs provides high reproducibility and reduces the user’s influence on the results to a minimum.Tasks and applications
