Scientifically Based Foam Analysis: Foam-Ability, Stability and Drainage

Krüss (Germany) have introduced the DFA100 Dynamic Foam Analyser and put together an all-round package for foam analysis. Almost anyone wanting to analyse foam production or prevention will find a competent ally in the DFA100.

Volumes from 20 ml are foamed with high reproducibility in the column using a gas stream or stirrer. The volumes of foam and liquid are determined continuously and without contact. Thanks to the high sampling rate, the unit even measures very unstable foams.

The software provides characteristics; such as decay half-life or values analogue to Ross-Miles in passing; while it determines the transition from pure drainage to decay and the end point of drainage, using new patented parameters. The measurement can be parameterised very flexibly.

It has a space-saving design, rapid column change with easy cleaning, and its automatic, statistically evaluated repeat measurements make it convenient. In addition, it has an option to measure on several columns simultaneously and independently is exceedingly time-saving.
