Measurement Of Spinning Drop Interfacial Tension Meter is research-based type from USA KINO, which adopts such technologies as removable and both-ends-fixed sample tube sampling mode (RBSM), full-self-sealed quartz glass tube (FSGT)£¬gas-thermal temperature control mode (GTCM)£¬and build-in heating system. The instrument can be used to measure interface tension down to 10-6mN/m for analysis of dynamic interface tension, interface rheology and interface viscosity (oscillating drop method), surface elasticity, relaxation study, etc. It can be applied in fields of personal care product, tertiary oil recovery, micro emulsion, surfactant and more.
¡¡¡¡Measurement Of Spinning Drop Interfacial Tension Meter 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.
