Features: interfacial tensiometer model TX500H is the newest variant of interfacial tensiometer/contact angle meter from USA KINO to meet comprehensive needs for analysis of contact angle, surface free energy and interface tension in tertiary oil recovery
Spinning drop interfacial tensiometer model TX500H is the newest variant of interfacial tensiometer & contact angle meter from USA KINO, which represents USA KINO’s most core technology of interface chemical instruments. This instrument fundamentally meets comprehensive needs for analysis of contact angle of solid-liquid, surface free energy of solid-gas and interface tension of liquid - liquid in tertiary oil recovery, which is the most powerful assistance for interface chemistry analysis in research institution of oil field, production institution, and universities.
Spinning Drop Method Used For Ultra-low Interfacial Tension Measurement
Under conditions of constant temperature and constant pressure, interface energy increases as interface area increases. The increment of interface energy per unit area is referred to as interface tension, which is formed for the different attractive forces of molecules on both sides of interface to molecules on the interface. Spinning drop interfacial tensiometer can accurately analyze low / ultra-low interface tension, while normal methods such as Wilhelmy plate method and Du Nouy ring method are incapable of measuring such low values.
In general, interface tension of 10-2-10-1mN/m is referred to as low interface tension, and that of below 10-3mN/m as ultra-low interface tension.
To measure ultra-low interface tension, the original balance between gravity and interface tension should be artificially altered to enable the shape of balanced droplet can be easily measured. Making system rotate to increase action of centrifugal force field is the measurement principle of spinning drop method. As shown below.

Applications
●Tertiary oil recovery
●Emulsion and polymer
●Pharmaceutical, pesticide, paint and coating
●Cosmetics and food industry
●Surfactant, soap & detergent
It’s recommended to purchase full auto surface / interfacial tensiometer A601 / A101 for higher accuracy when the interface tension is above 1mN/m.
Comprehensive functions and budget-friendly
This instrument can complete both functions of optical contact angle meter and spinning drop interfacial tensiometer, which can be used to measure interface tension of liquid-liquid / liquid-gas, contact angle of liquid-solid, solid’s surface free energy and its distribution, e.g. dispersive force, polar force, hydrogen bond value, Lewis acid, as well as wetting behavior analysis of solid material, and all other chemical parameters.
Diversified analytical methods
The instrument can enable analytical methods of spinning drop, pendant drop, sessile drop, tilted plate and more, which can meet extensive and complex measurement requirements in interface chemistry.
