Dynamic Contact Angle Meter and Tensiometer (DCAT 21)

  • Description:

    The device is used for software-controlled determination

    - the contact angle of powders and fiber bundles as well as the adsorption behavior of liquids on wettable materials according to the Modified Washburn Method

    - of the dynamic contact angle and surface free energy on prismatic and cylindrical specimens 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 bracket method or the Du Noüy ring method with automatic ring correction according to Huh & Mason, Zuidema & Waters, Harkins & Jordan
