The K121-program offers the following opportunities:

• Measurement of advancing and receding contact angle with the wilhelmy method together with the following calculation of the surface energy of solid with several methods.
• Measurement of the adsorption properties of porous and sucking material with the rising height method and following calculation with the Washburn equation.
• Measurement of the surface tension of liquids with the Wilhelmy plate method.
• Determination of liquid densities.
• Determination of fiber diameters

 

The K121-program offers the following opportunities:

• Measurement of the surface tension with the ring method and the plate method.
• Controlling series of measurements with dosimate for the CMC-determination.
• Measurement of the interfacial tension with ring- or plate methods. With the ring method, measurements in pull or push direction can be performed.
• Determination of synergistic effects from collections of single CMC-measurement.
