Overview
The TX500C rotary droplet interfacial tension meter is easier to operate and has a more stable system. Its main application areas include indoor research and on-site monitoring of tertiary oil recovery (chemical flooding) in oil fields; Research on surfactant, detergent, emulsion and foam; Research on fuel oil, lubricants, paints, inks, and coatings; Research on pharmaceuticals, paper products, photosensitive materials, pesticides, and other related fields. Different from typical interfacial tension testing, the rotating drop testing technique can analyze low interfacial tension, while conventional methods such as platinum plate method and platinum ring method cannot achieve such measurements. Usually, we refer to the interfacial tension of 10-2-10-1mN/m as low interfacial tension, while the interfacial tension below 10-3mN/m is called ultra-low interfacial tension. To determine ultra-low interfacial tension, it is necessary to artificially alter the balance between gravity and interfacial tension of the system, so that the droplet at equilibrium is closer to the ideal shape for measuring interfacial tension values. This can be achieved by rotating the system and increasing the effect of the centrifugal force field. This is the principle of ultra-low interfacial tension testing for rotating droplets.
