Many questions about foam, one universal approach: The DFA100 Dynamic Foam Analyzer measures the foamability of liquids and the stability of quickly decaying or long lasting foam based on reproducible foaming and height detection. With optional modules operating in parallel, it also measures the liquid content or analyzes the foam structure with regard to bubble size and distribution. The DFA100 supports you in optimizing foam-forming products or helps you to avoid unwanted foam formation.

Applications
• – Firefighting foams
• – Flotation as a method for separating solids
• – Foam prevention for paints and varnishes, process and waste water, or cooling lubricants
• – Foam-inhibiting and foam-reducing agents (anti-foaming agents/defoamers)
• – Foams for washing and cleaning
• – Foams in food and personal care products
• – Surfactant development

Measuring methods
• – Foamability and foam stability using the optically detected height of foam created reproducibly
• – Foam formation behavior of heavily foaming liquids using stirring cycles
• – Optically detected foam bubble sizes and their statistical distribution
• – Moisture and drainage behavior of foam using its electrical conductivity
• – Carrying out a measurement up to 20 consecutive times and displaying the results together
