Dynamic contact angle measurement
The contact angle is a parameter used to analyse the wetting behaviour of a liquid on a solid surface. The static contact angle describes the state in equilibrium. Dynamic contact angles describe a drop of liquid that is in motion. For example, this means measuring while a drop rolls off a tilted solid surface.

Application notes

Determining the critical micelle concentration for biosurfactant using DataPhysics DCAT
DataPhysics dynamic contact angle measuring devices and tensiometer (DCAT-11) equipped with a liquid-dosing unit (LDU) were used in this research.  


DataPhysics DCAT product series
The dynamic contact angle measuring devices and tensiometer of the DCAT series are universal measuring devices, that allow to investigate numerous surface and interfacial properties.
