The handy LAUDA bubble pressure tensiometer MPT C records fast surfactants in millisecond range.
Ultimate user-friendliness is achieved without having to take a detour via the PC. The extremely compact stand-alone device offers all the
necessary features for the simple measurement of dynamic surface tensions in the laboratory or as a mobile device.
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 20 seconds
- Simple measurement of higher-viscosity and biological solutions
- Exact determination of concentrations above the critical micellar
concentration
- Monitoring 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
Performance profile and advantages:
– Extremely large dynamic range from 1 ms up to several seconds
– Automatic recognition of the transition point bubble/jet range
– Tabular representation of the dynamic surface tensions,
number of measured points, real bubble age
– Graphic representation of the dependency of the dynamic surface
tensions on the bubble age, linearly or logarithmically
– User-defined measuring point distance and duration of the measurement
– Storage of up to 50 measured results including the accompanying
parameters
– Numerical description of samples determined by the user
– Output of the measured values on an optional printer or PC via
RS 232-interface
– Plug-in boards with relay output in order to control the processes via
the surface tension
