Spinning drop interfacial tension / Intravenous contact angle

Spinning drop interfacial tension contact angle measurement is based on the latest research results of domestic surface and colloid chemistry experts, integrated the advantages of similar products at home and abroad, using computer control and multimedia technology in the new millennium of the latest research and development of products. The instrument uses a spinning drop method; It is a special equipment to measure the surface tension of liquid, liquid / liquid interfacial tension and liquid / solid contact angle. The main application areas are: EOR (chemical flooding) indoor study and site monitoring; study of surfactants, detergents, emulsions and foams; research fuel oil, lubricants, paints, inks and coatings; paper products, photographic research materials, pesticides, etc.,
Main application areas
1. EOR (chemical flooding oil) indoor and field monitoring study
2. surfactants, detergents, emulsions and foams study
3. Study of fuel oil, lubricants, paints, inks and coatings
4. Research paper products, photographic materials, pesticides etc

Feature
1. The whole process is controlled by PC computer and a pre-SBC, the use of computer multimedia video technology to collect spinning drop of image analysis,
2. The master program is a Windows interface, easy operation, the image as a standard BMP file that can be stored in print.
3. The tension measurement wide range, from 10-5mN / m to 100mN / m, across seven orders of magnitude, the meter full scale tension.
4. The high accuracy, providing the number of stalls magnification, hair width can be enlarged to over one hundred pixels, greatly improve the measurement accuracy of ultra-low interfacial tension.
5. One machine can measure the interfacial tension and contact angle, thereby performing wet ability studies. For contact measurement under normal circumstances, the instrument can make liquid droplets in a regular rotation of the body, thus ensuring measurement precision and accuracy. In addition, it can also be measured when the contact angle of the liquid / liquid interfacial tension of ultra-low value, and very convenient, this is the other contact angle measuring instrument difficult to do.
6. With electric heating temperature control system, capable of constant temperature experiments.
