Description

We are offering Bubble Pressure Tensiometer BP100 that has a software-controlled flow of air emerging from a capillary that produces air bubbles in the sample. It is known that printing, bonding, spraying and cleaning processes require surfactants that are already effective in fractions of a second, along with an instrument that can record their effectiveness. It is used to determine the dynamic surface tension as a function of the surface age. Thus, the instrument provides information about wetting and drop formation in rapid processes. Besides, our Bubble Pressure Tensiometer BP100 that has a built-in compressor, is the instrument, which does not need an external compressed air connection. To ascertain the maximum pressure during bubble formation, from which the surface tension is calculated, a high-precision pressure sensor is provided. Without any problems, the user can avail thermostatted measurements.

LabDesk software enables the automatic control of scans with an almost unlimited resolution over a wide range of surface ages. Measurement also supplies the equilibrium value according to Hua & Rosen, apart from the time-dependent surface tension. Important parameters, where the mobility of surfactants is concerned, namely diffusion and adsorption coefficients, can be calculated from surfactant concentration series. For allowing further insights, like for concentration or temperature comparisons, measurements at constant bubble ages are applied.

The measurement is carried out fully automatically up to data output in the form of a plot, after a minimal preparation period. Results and evaluations appear in a comprehensive report, with a mouse-click measuring parameters. For all KRÜSS tensiometers data from other instruments to be included, LabDesk™ software platform is an effective tool.
