Dynamic Contact Angle Measuring device and Tensiometer

The DCAT 21 is the latest model with new and advanced features representing now the most sophisticated Dynamic Contact Angle Tensiometer on the world market today. Besides the excellent software-controlled measurements of dynamic contact angle, surface free energy, static and dynamic surface/interfacial tension, liquid density, wetted length, sedimentation study, absorption kinetics, etc, other options are available for such features as the Non Magnetic version, the temperature control unit TV xx with a removable micro-electronic stirrer system, just to name a few. For detailed, please speak to one of our surface science specialists at FDS (Phone:516-349-0663).

The DCAT 21 consists of the basic instrument with the following technical equipment:

  • The contact angle of powders, single fibers and fiber bundles and the adsorption behavior of liquids on wettable materials according to the modified washburn method
  • The dynamic contact angle and the surface energy prismatic and cylindrical samples according to the Wilhelmy method
  • The static surface and interfacial tension of liquids
  • the critical micelle formation concentration of surfactants (CMC) according to the Wilhelmy plate method
  • Lenard frame method or the Du No? ring method with automatic ring correction according to Huh & Mason, Zuidema & Waters and Harkins & Jordan, as well as for fully automated reproducibility measurements

The DCAT 21 consists of the basic instrument with the following technical equipment:

  • High-precision electro-dynamically compensated weighing system with automatic calibrating function
  • Software-controlled motorized height positioning of the sample vessel with variable speed
  • Automatic balance lock
  • 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
  • Pt100 temperature sensor for the installation in the temperature control unit
  • It is prepared for the installation of a liquid temperature control unit TV 50, TV 70 or TV 100 with integrated
  • Magnetic stirrer for mounting either of the sample vessels made of borosilicate glass (with diameters 50,70 or 100 mm).
  • The 32-bit NT based software SCA 200 developed for Windows 2000/XP offers by various expansion steps. The analyses according to different methods were build-in the software
  • It is prepared for the installation of a fluid circulation temperature control unit with an integrated magnetic stirrer for mounting either one of the sample vessels TV 50 / TV 70 / TV 100.
