The DFA 100 Dynamic Foam Analyzer provides information about foamability, stability and drainage. Volumes from 20 mL are foamed with high reproducibility in a column using a gas stream or stirrer. The volumes of the foam and liquid are determined continuously and without contact. A high sampling rate enables the unit to measure even unstable foams. Software provided with the device provides characteristics such as decay half lifes or values analogous to Ross-Miles in passing, while it determines the transition from pure drainage to decay and the endpoint of drainage using new, patented parameters. — Krüss GmbH, Hamburg, Germany
