The DFA100 Dynamic Foam Analyzer measures the foamability of liquids and their related stability e.g. rate of foam decay or longevity based on reproducible foaming and height detection.

Set-up includes modules that allow liquid content and foam structure (bubble size and distribution) to be determined.

Min. recommended sample volume 50 mL with 40 mm diameter column
