Applications

LAUDA tensiometers offer a comprehensive range of measuring tensiometry equipment, for high accuracy determination of dynamic, interfacial and surface tension of liquids, oils and numerous other solutions.

For rapid processes

The fast adsorption processes of surfactants used in many applications are frequently not measurable using conventional tensiometers. Only the bubble pressure tensiometer enables the generation of short-life surfaces and measurement of the dynamic surface tensions that occur on those surfaces. The unique bubble pressure method used in the MPT 2 allows an optimised recording of the dynamic characteristic curves of surfactant solutions down into the sub-millisecond range.

Application examples

• Optimisation of drop sizes
• Determination of surfactant consumption
• Measurement of dynamic surface tensions in a time range of below one millisecond up to 50 seconds
• Simple measurement of higher-viscosity and biological solutions
• Exact determination of concentrations above the critical micellar concentration

As a surfactant monitor, the MPT 2 monitors processes with an online flow cell and extended software functions:

• Surfactant production
• Surfactant content in waste and cleaning water
• Washing processes and their surfactant consumption
• Wetting agent content of coating solutions during print processes
