The SDIT-500C spinning drop interfacial tensiometer generates a centrifugal force field through high-speed rotation, altering the balance between gravity and interfacial tension in the system, thereby achieving accurate measurement of low/ultra-low interfacial tension (down to 10⁻⁷ mN/m). With its superior system stability and user-friendly operating system, SDIT-500C has become a reliable tool for interfacial science research. Its applications are wide-ranging, covering laboratory research and field monitoring in tertiary oil recovery (EOR), performance evaluation of surfactants and foam systems, R&D and quality control of industrial products such as fuel oil, inks, and coatings, as well as interfacial behavior research in pharmaceuticals, paper products, photosensitive materials, and pesticides.
Spinning Drop Interfacial Tensiometer Feature:
The interfacial tension measurement spans eight orders of magnitude, making it a full-range rotating droplet interfacial tension measuring instrument.
Employs a Swiss-imported brushless high-speed motor with a long service life, a controllable speed up to 12,000 rpm, and a controllable speed accuracy of ±5 rpm.
The camera and objective lens combination ensures high measurement accuracy and offers multiple magnification levels, enabling the amplification of ultra-low interfacial tension oil droplet filamentation, significantly improving the measurement accuracy of ultra-low interfacial tension.
Employs PID temperature control technology; the instrument is also compatible with external super-thermal bath temperature control.
Utilizing intelligent graphics AI technology to acquire and analyze images of rotating droplets offers superior operability and repeatability.
Precise LED control technology results in clearer imaging of interface edges, which is beneficial for analyzing the interface edges of turbid oilfield samples.
Quartz glass tube sheath insertion and removal technology making it easy to operate and less prone to breakage.
The inner sleeve and rotor are made of stainless steel, ensuring a long service life, providing high stability, and facilitating heat conduction.
Imported chip USB-compliant digital CCD enhances user convenience and freedom of use.
Camera soft trigger: The camera directly communicates with the Z-phase signal of the motor encoder, enabling faster and more accurate image capture.
