The dynamic contact angle measuring device and tensiometer DCAT 25 is the multifunctional all-round instrument of the DCAT series. The weighing system is even more precise than that of the DCAT 9 and 15 and hence offers highest accuracy for the determination of surface and interfacial tension. A completely closed sample chamber enables measurements under inert gas or ionised atmosphere as well as with controlled relative humidity.

Due to the longer travel distance of the sample stage, an electrical temperature control unit can be mounted inside the DCAT 25 which makes measurements at temperatures of up to 300 °C possible. Moreover the Langmuir trough module can be used to investigate the surface pressure and the interfacial rheology of monolayers. The upgrade video system provides the opportunity to record video-sequences during force of adhesion measurements and to evaluate contact angle, contact area etc. in addition to the force. The optional TP 50 control panel with touch screen and precision control wheel ensures an intuitive and fast device control even during complex measurements.
