Spinning drop interfacial tension meter

Description
SIT2000C type spinning drop interfacial tension meter is based on its own products and integrated part of the US fusion technology, according to the latest research results of domestic surface and colloid chemistry experts, using computer control and multimedia technology. It is developed by the improvement of the classic plug type injector tube system, anti-corrosion stainless steel heating system and image acquisition technology based on SIT2000B type. This product is easier to operate and more stable. The main application areas are: oil EOR (chemical flooding) indoor study and site monitoring; study of surfactants, detergents, emulsions and foams; research fuel oil, lubricants, paints, inks and coatings; pharmaceutical, paper research products, photographic materials, pesticides and so on.
Feature
1. The instrument uses a quartz glass tube pluggable manner, spring thimble against the sample tube, automatically pop up when removing the sample tube easily broken. When injecting the sample into the test again, easier to clean, more convenient operation. Since the inner sleeve made of stainless steel and stainless steel rotor, expansion coefficient of convergence is conducive to temperature conductivity, the material is not susceptible to corrosion and rust, high concentricity, easier to maintain sample tubes horizontally stable, easy to shake.
2. The whole process is controlled by PC computer and pre-SBC, the use of computer technology to collect spinning drop multimedia video images to analyze, calculate, has a very good maneuverability and repeatability.
3. The latest precision LED control technology, the next image acquisition trigger mode, low-speed and high-speed rotation conditions are not flashing screen, the image is sharper edge interface, useful for analyzing oil samples turbid fine features.
4. The master program is Winndows interface, easy operation, the image as a standard BMP file that can be stored in print. Program uses the world's most advanced computing technology interfacial tension measured value, simply press the "test", our software automatically controls the speed camera, save the images to calculate interfacial tension value, showing the measured values, the process without human intervention, so as to effectively avoid the human factors on the measured value. You can record the value of interfacial tension with time, speed, temperature changes and all measured values ​​are stored in the database, and export directly to EXCEL documents to be displayed in real-time graph of the measured values. User-friendly software design, powerful database management manage all test data.
5. The interfacial tension measurement is wide range, from 10-6mN / m to 100mN / m, across eight orders of magnitude for the whole range of the tension gauge.
6. The use of US imports PITTMAN high-speed motor, servo control system has a complete motor control system upgrades and better compatibility, speed control up to 10,000 rev / min, speed control accuracy is ± 5 rev / min, motor encoder control points up to 500 points / turn, more accurate, more convenient manipulation. High accuracy, the number of stalls providing magnification, hair width can be enlarged to over one hundred pixels, greatly improve the measurement accuracy of ultra-low interfacial tension.

7. With electric heating temperature control system, capable of constant temperature experiments. The instrument uses a precise PID temperature control technology, heating assembly with a new corrosion resistant stainless steel design, fast heat conduction and easier to uniformly heat the sample tube not need to meet other temperature control equipment, instrument can also choose a super bath temperature control, two temperature control system compatible.
8. Low noise electric viewfinder mechanism interface button operation, simple and convenient. Three leveling design makes it easy to control droplets in the range of available window.
