As is well known, nanomaterials science and engineering have become a global research hotspot. When studying surface modification of nanomaterials, the concept of wetting contact angle is often involved. The so-called contact angle refers to the angle formed when a liquid droplet is dropped on a solid horizontal plane, and the gas-liquid interface and solid-liquid interface tangent lines sandwich the liquid phase at the boundary point of the solid liquid gas three-phase on the surface of the solid. The JC2000C1 contact angle measuring instrument is mainly used to measure the contact angle between liquid and solid, that is, the wettability of liquid to solid, and can also measure the contact angle when the external phase is liquid. This instrument can measure the contact angle of various liquids with various materials, such as block materials, fiber materials, textile materials, etc. Powder samples can also be measured after compression. At the same time, this series of instruments can measure and calculate surface/interface tension CMC、 Droplet shape and size, surface free energy, advance angle, retreat angle, etc.

Characteristics of JC2000C1 Contact Angle Measuring Instrument
1. By using computer multimedia technology, optical system, and CCD camera, the image of the droplet is displayed clearly on the computer screen, and the image can be stored instantly for measurement use, avoiding measurement failure caused by liquid evaporation.
2. It has three image modes: instant freezing, automatic continuous photography, and high-speed photography, ensuring accurate measurement even for volatile liquids. Meanwhile, the external tangent line is the most affected issue by subjective human factors. The JC2000 series contact angle measuring instrument integrates geometric calculations into software, eliminating the need for manual judgment of contact angles.
3. The overall structure of the instrument includes a four-dimensional motion adjustment mode.

JC2000C1 contact angle measuring instrument with tax included shipping price：RMB 41800.00 per unit, price does not include supporting computer, including instrument host, experimental operation software, standard components, free on-site installation and debugging training in major cities in mainland China, one-year warranty service, and lifelong free software upgrade.

JC2000C1 Contact Angle Measuring Instrument with Computer：The JC2000C1 contact angle measuring instrument must be equipped with a matching computer before use. If the supplier chooses to provide the matching computer, an additional payment of 4000 yuan per unit must be made to the supplier. DELL computer comes with a three-year on-site warranty from the original factory. If the user configures or uses the existing computer, a blank USB 2.0 interface is required. Laptops, desktops, and all-in-one computers are all acceptable.
