Optical system: not less than 400 images / second, resolution: 656 x 494 pixels, 6.5 times zoom lens, magnification 0.7-4.5, IEEE 1394 Interface Interface 9. * Displacement System: Automatic X-axis sample stage, can at set intervals, dropping the sample to the set position of the substrate contact angle of Chengde, to achieve process control multi-point test. Motor sports range: X = 150 mm, precision motion:. 0.1mm10 tilt sample stage: 11. * manual titration system: automatic single-channel injector containing a type sample pipette, nominal injection capacity 200μl or 1000μl (nominal injection capacity 200μl, maximum injection capacity 140μl), injection precision 0.2μl, made of polypropylene and PFA needle. As we all know, nano-materials science and engineering has become a worldwide hotspot in the study of surface modification of nano-materials, often involves wetting contact angle of this concept. So-called contact angle is the drop on a solid horizontal plane in a droplet on a solid surface solid - liquid - gas three - phase junction point, the gas - liquid interface and solid - liquid interface between two tangents when the folder in which the liquid phase the angle formed. JC2000A Intravenous contact angle / interfacial tension gauge is based on the improvement JC98A contact angle measuring instrument, Dongguan Sheng Ding contact angle, for measuring the contact angle of the liquid to the solid contact angle that the liquid on the wettability of the solid German g Lu Shi contact angle, the Foreign Secretary also measure contact angle of the liquid. The instrument can measure a variety of liquid contact angle of various materials, such as bulk materials, fiber materials, textile materials, powder samples can also be measured in the tablet. In addition, the instrument can also measure the advancing angle and receding angle. The instrument of oil, printing and dyeing, pharmaceutical, coating, processing and other sectors of research and production has a very important role, especially used in surface modification of materials research more prominent, the other can be used as laboratory equipment Teaching. Germany Shi grams companion contact angle, contact angle, angle of water droplets provided by the Dongguan City Ding Sheng Precision Instrument Company.
