DCAT 15 Tensiometers

The DCAT 15 Tensiometers enables additional measuring methods and hence can be used to determine dynamic contact angles, the surface energy of solids or sedimentation and penetration properties. In addition the DCAT 15 can be extended with a liquid dosing unit LDU 25 and can thus create sequential concentration series of, for example, surfactant solutions. Without manual user intervention the critical micelle concentration (CMC) can be determined software controlled in a series of experiments.
