Foam contact angle measurements
To study the foaming tendency of liquids and the efficiency and working principle of defoamers, the Dynamic Contact Angle Meter SDC-500 is the appropriate device for this application. It foams samples in multiple, highly repeatable ways while continuously measuring foam and liquid volumes. For a deeper understanding of foam formation and decay, measurement modules for liquid content and foam structure complement the analysis. The Interfacial Rheology Module provides a complete scientific solution to correlate foamability, foam stability with physical parameters such as elastic and viscous moduli.
Methods for foam analysis of foaming liquids
Foam is a beneficial companion to many products, such as shaving foam, where the product itself is foam. Developers and quality managers in various fields need to define foam formation, stability, moisture and foam internal structure. Our foam analyzers meet the measurement needs of industry and science for foam-related jobs and problems.
Foamability
The need for the foamability of liquids covers a wide range of areas, for example the production of fire fighting foams requires the production of large volumes of foam with relatively small amounts of liquid. In contrast, such efficient foaming is undesirable when brushing. Utilize our dynamic contact angle meter SDC-500 to foam samples in a variety of highly repeatable ways while simultaneously measuring foam and liquid volume in real time.
Foam stability
Different requirements for foam stability generally depend on the product type, such as metastable foam for beverages and stable foam for whipped cream. Reliable foam decay data is required to obtain the desired stability, and measuring foam height over time enables observation of foam volume reduction during different decay processes.
