NameTop view optical contact angle measuring instrument

Contact angle refers to the tangent line of the gas-liquid interface at the intersection of gas, liquid, and solid phases. The angle θ between this tangent line and the solid-liquid boundary line on the liquid side is a measure of the degree of wetting. It is currently the main method for surface performance testing. Using the principle of optical imaging, measure the contact angle, wetting properties, interfacial tension, forward and backward angles, surface energy, etc. of the sample surface. It mainly consists of a light source, an injection unit, a sample stage, a collection system, analysis software, etc. The equipment adopts an automatic liquid inlet device, which has high cost-effectiveness, strong scalability, and comprehensive functions, and can meet various conventional measurement needs. It has been widely used in many universities, colleges, and enterprises.

.

Evaluation of solid surface treatment, analysis of plasma cleaning effect, analysis of surface cleanliness, study of adhesion characteristics between solid and liquid or solid, design of liquid formula, characterization of surface printing performance, analysis of surface modification, study of surface wettability of glass (including solid materials such as plastics or metals), etc. Contact angle measurement has become an important instrument for evaluating surface performance in fields such as mobile phone manufacturing, surface treatment, material research, chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textile fibers, medical biology, etc.

As is well known, software is the soul of an instrument. Although the hardware that makes up the system provides the foundation for measurement, it can only be achieved with the support of softwareRealize the functionality of hardware, fully unleash its potential, and enhance the overall functionality and performance of the system like a tiger.

Our company has been providing customized CA V2.0 static/dynamic contact angle measurement software and surface energy measurement software specialized measurement and control software to customers since 2010. After 10 years of customer feedback, usage requirements, integration of national and foreign standards in the adhesive tape industry, it has reached a very mature and stable state.

Software control systems with independent intellectual property rights (which are rare in the industry) play a significant advantage in future software upgrades and standard changes, ensuring that testing methods and standards are at the forefront of the industry.

Fine Machinery: The framework of the system is made of high-quality imported high-strength oxidation protected aluminum profiles and treated with baking paint. All other major components are also made of aluminum alloy, stainless steel, and copper alloy through precision manufacturing. Ensure strong stability of the instrument.

Precision positioning: All linear moving units of the system, including the 3D sample stage (xy axis), (Z-axis) injector/needle movement adjustment, are driven by linear copper racks and precision dovetail grooves to ensure smooth, easy, and precise transmission.

Fully equipped injector and needle selection: dozens of different specifications of injectors are provided for users to choose from, such as different specifications (25ul/50ul/100ul/250ul/500ul/1000ul...), different materials (airtight glass injector/plastic injector), different brands (Hamilton/poli...) to meet different customer needs. We offer various specifications (10-34 #) and different materials (stainless steel/PTFE/PP flexible needles) as well as special needles (curved needles), which can be used for routine contact angle measurement, as well as for injection and droplet transfer of special liquids such as superhydrophobic, superhydrophilic, and high viscosity.

Imaging system: Adopting a high-resolution CMOS image sensor with Rolling Shutter and a 0.7-4.5 telecentric contour lens. Guaranteed imaging effect. The high-intensity backlight cold light source with continuously adjustable brightness provides uniform background illumination for imaging. High quality lenses and high-resolution cameras can display droplets in images with ideal size and brightness, even very small droplets.

Software platform: Software is the soul and brain of the entire measurement system. CA V2.0 software provides users with a wide range of functions and features, and many of its projects are outstanding in this field. As an optical method, the accuracy of measurement depends on the quality of imaging and subsequent processing, analysis, and calculation methods. The core components of the software include sub-pixel droplet coordinate detection, automatic liquid/solid/fluid three-phase contact line recognition, droplet full contour analysis, and droplet monitoring function based on continuous information feedback, all of which can be completed in real-time. Equipped with automatic measurement and fast fitting function of bilateral contact angle, it can analyze the wetting performance of liquid and solid surfaces, and more accurately analyze the actual wetting situation of the surface.

The software automatically generates reports, including various data reports such as Word, Excel, PDF graphics, spectra, etc.

Provide contact angle measurement calibration samples imported from Germany to ensure the accuracy of the instrument, with angle calibration standards of 5 °, 8 °, and 30 ° (optional); 60 °, 90 °, 120 ° (optional).

The baseline automatic tilt function can correct differences caused by sample tilt or machine tilt.

Hierarchical management system, permission management. Separate experimenters and administrators. To avoid human data manipulation affecting test results.
