Product Overview

The KRUSS DFA​100 Dynamic Foam Analyser is designed for high performance optical testing of fluid foam structures and stability. It supports the optimisation of of foam forming or foam prevention products, analysing the entire spectrum, from slow to very fast decaying foams. The instrument can also measure foam structure with regards to bubble size and distribution or the liquid content of the foam.

The DFA100 uses optical sensors, either blue LEDs or Infrared light for opaque liquid foam to dynamically measure the quantity of the foam produced. It determines the number, size and size distribution of the bubbles and the decay characteristics over the whole measuring cylinder height.  Simultaneously the quantity of discharge of liquid from the foam (drainage) into the liquid pool is measured by the same senor to provide a more complete understanding of the dominant decay phenomena.

The DFA100 can provide accurately controlled foaming in a variety of ways most commonly by pushing air or CO2 through a glass filter plate or by stirring using a blade in any customisable shape. Foam can also be created externally for subsequent analysis or at high temperature up to 90°C. The measurement chamber can be completely removed for ease of cleaning.

ADVANCE is an intuitive software platform for foam analysis where all measurement parameters are customisable and every measurement can be fully automated. It is easy to use, allows live observation and provides numerous reports to compare measurements across different samples.
