Particle & Surface Sciences  have introduced the Dataphysics DCAT 11 dynamic contact angle meter and tensiometer.

The DCAT 11/11EC is used for the software-controlled measurement of the contact angle of powders and fiber bundles and the adsorption behaviour of liquids on wettable materials according to the modified Washburn method.

The DCAT 11/11EC is used for the dynamic contact angle and the surface energy of prismatic and cylindrical samples according to the Wilhelmy method.

The DCAT 11/11EC is also used for the static surface and interfacial tension of liquids and the critical micelle formation concentration of surfactants (CMC) according to the Wilhelmy Plate method, Lenard Frame method or the Du Noüy Ring method with automatic ring correction according to Huh & Mason, Zuidema & Waters and Harkins & Jordan as well as for fully automated reproducibility measurements.

The Dataphysics DCAT 11 dynamic contact angle meter and tensiometer consists of the basic instrument with the following technical features:

  • High-precision, electrodynamically compensated weighing system with automatic calibrating function
  • Software-controlled motorised height positioning of the sample vessel with variable speed
  • Integrated measuring and control electronics with digital thermometer
  • Graphical display for weighing data, temperature and other measuring statuses
  • Serial RS 232C interface with PC connecting cable
  • Illuminated sample chamber with connection for inert gas
  • Sample vessels of borosilicate glass available with diameters of 50, 70 and 100mm
  • Pt100 temperature sensor for installation in the temperature control unit
  • Du Noüy ring RG 11, made of platinum-iridium to DIN 53914
  • Wilhelmy plate PT 11, made of platinum-iridium to DIN 53914
  • It is prepared for the installation of a liquid temperature control unit with integrated magnetic stirrer for mounting either of the sample vessels TV 50/TV 70/TV 100
