Molecular Interfacial Tension Meter

The molecular interfacial Tensiometer analyzes intermolecular forces by measuring the interfacial tension between liquids and gases or between liquids. It is used for testing the wettability of coatings, evaluating the adhesion of inks, and adjusting printability. Its principle is based on calculating surface tension values using the Wilhelmy plate method or the pendant drop method.
Selection
When selecting, consider that the measurement range covers the sample tension values and the accuracy matches the testing requirements. Pay attention to the temperature control function to ensure it adapts to the experimental environment, and verify that the sample-compatible materials are corrosion-resistant. The operation interface should align with the personnel's usage habits, and the data output format should be compatible with the existing system.
