Name:
high pressure and temperature spinning drop interface tensiometer
Model:
TX500HP
Description:

High pressure and temperature spinning drop interface tensiometer model TX500HP is special designed for measurement of interface tension (IFT) between liquid-gas/liquid-fluid system under high pressure and high temperature.

High pressure and temperature spinning drop interface tensiometer model TX500HP  is special designed for measurement of interface tension (IFT) between liquid-gas/liquid-fluid system under high pressure and high temperature. Max pressure can reach to 70MPa and temperature range is between -30-200. IFT measurement via pressure and temperature is very useful for application such as Enhanced Oil Recovery (tertiary oil recover). TX500HP can be used to measure IFT between ASP or binary liquid mixture systems and crude oil in the simulated condition with high pressure and temperature with min value about 107mN/m. And beyond that, it can be used to measure IFT of your system with compressed liquid gas such as CO2 or natural gas with extra connector port for gas system.High pressure and temperature spinning drop interface tensiometer model TX500HP is special designed for measurement of interface tension (IFT) between liquid-gas/liquid-fluid system under high pressure and high temperature.

ultra high pressure and temperature spinning drop interfacial tensiometry

interfacial tensiometerHigh Pressure And Temperature Spinning Drop Interface Tensiometer 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:
