Spinning drop interfacial tension meter

Description
Based on SIT2000C type spinning drop interfacial tension instrument, it is developed by the improvement of the classic plug-in injector pipe system, anti-corrosion stainless steel heating system and image acquisition .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. Improved quartz glass instrument 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 PC computer and pre-SBC is controlled by the use of computer technology to collect spinning drop multimedia video images to analyze, calculate, has a very good maneuverability and repeatability.
3. Using the latest precision LED control technology while updating the high-speed acquisition and trigger mode CCD image acquisition under 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 Windows interface, easy operation, the image as a standard BMP file that can be stored in print. The program uses the world's leading 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. interfacial tension measurement 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 motor control with complete system upgrades and better compatibility, speed control up to 10,000 rev / min (also choose higher speed 14,000 rpm / min motor), precision can control the speed of ± 5 rev / min, motor encoder control points up to 500 points / turn, more accurate, more convenient manipulation. Increased precision arc pendulum platform and one-dimensional focusing platform that enables high measurement precision, while providing a number of stalls 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. Optional SIT2000B classic type rotary swing mechanism, the balance in favor of drop placement. More high-end automatic optional viewfinder, the testing process no longer need to manually adjust the position of the droplet, easier to operate.
9. Fusion new technology industrial touch screen and networking technology, the Internet keeping with the times + innovative products.
