Why do we need a bubble pressure tensiometer?
The SITA bubble pressure tensiometers permit an uncomplicated measurement of the dynamic surface tension even from a small sample. A wide range of adjustable bubble lifetimes (surface age) allows a survey of the kinetic characteristics of surface active components in the liquid. The interface (air/sample), which is crucial for measuring, does not have to be cleaned after reading because with every new bubble the interface is freshly created.
