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
