PL21

Standard measuring probe for the Wilhelmy plate method

  • Bookmark

The PL21 is our proven plate geometry for measuring surface and interfacial tension using the Wilhelmy plate method. The dimensions of the plate comply exactly with the form specified in international standards and thus enable a high level of repeatability for the analyses.

 

As the plate is made of the precious metal platinum it has an extremely high free surface energy and therefore also the required excellent wetting properties. These are further optimized by the homogenously roughened surface of the plate. A high-quality protective box is provided for its safe storage.

A PLC21 version of the plate with a certificate from an independent testing institute is also available.
