Wilhelmy Plate

A Wilhelmy plate is a thin plate that is used to measure equilibrium surface or interfacial tension at an air–liquid or liquid–liquid interface. In this method, the plate is oriented perpendicular to the interface, and the force exerted on it is measured. Based on the work of Ludwig Wilhelmy, this method finds wide use in the preparation and monitoring of Langmuir–Blodgett films.

Famous quotes containing the word plate:

    Say “Yessum” to the ladies, an’ “Yessur” to the men,
    And when they’s company, don’t pass yer plate for pie again;
    But, thinkin’ of the things yer’d like to see upon that tree,
    Jes ‘fore Christmas be as good as yer kin be!
    Eugene Field (1850–1895)
