The understanding and measurement of the surface tension of liquids can be important in a wide variety of applications. Knowledge of the surface tension can allow the wettability of a liquid with a given surface to be estimated. This can be particularly important in relation to surfactants, inks and paints. For samples where large volumes are available the use of a classic tensionmeter based approach can be used employing the Wilhemy plate or DuNouy ring method. LPD uses a Dataphysics Dynamic Contact Angle Tensiometer (DCAT21). This system has the added advantage that the temperature of the liquids can be varied from room temperature up 80°C during the measurement. Alternatively, a pendant drop method can be used. This can be useful where only small sample volumes are available. LPD uses a Dataphysics Optical Contact Angle (OCA35) instrument. Using tensionometry or pendent drop methods it is also possible to measure the interfacical surface tension between non-micible liquids. Applications for surface tension data include:
Industrial applications of surface tension data include: Petrochemicals
