Introduction: This series is a fully automatic intelligent contact angle meter with a high degree of automation and excellent functionality. Including all functions of Type A, Type B, and Type C, and on the basis of it, we have added an automatic three-dimensional translation and lifting sample stage, combined with automatic sample adding device, and realized full-automatic, time-based, completely repeatable and controllable measurement methods. The principle of optical image analysis is used to bond CAM7.1TM professional interface chemistry analysis software to test and analyze the contact angle of liquid to solid (outer phase is gas or immiscible liquid), adhesion work, wet work, spread Coefficient, critical micelle concentration, liquid-vapor and liquid-liquid surface/interfacial tension, drop contour size, solid surface energy distribution (dispersion force, polarity force, van der Waals component, Lewis acid/base component), wettability Behavior analysis and so on. Features: 1. The whole frame: Based on an open design and modular concept, it is easy for the user to approach the various parts of the instrument during operation, and has good expandability, which can be added as needed After the main frame is professionally designed, it is made of light-weight, high-strength aluminum alloy CNC machining. The surface is sprayed with plastic, the structure is stable, and the appearance is beautiful. It is equipped with a horizontal supporting foot with strong carbon steel bearing capacity, which can be adjusted universally and vertically to ensure the levelness and stability of the whole machine. 2. Mechanical positioning platform: Focusing combination positioning table adopts precise differential head drive and threaded screw drive to achieve focal length positioning and pitch angle adjustment The lift-and-drop translation combination sample stage is controlled by software and driven by a stepping motor, which can realize automatic and rapid large-scale movement without generating the slightest shake and tilt. 3. Precision sampling system: The automatic sample adding device adopts software setting and control. The stepper motor drives the sampler and adds liquid. It can be equipped with multiple specifications of liquid sampler. The high-precision automatic sample adding device is controlled by software. The precision injection pump adds fluid through the pipeline. It is suitable for the measurement of the volume of the droplet that needs to be continuously circulated and accurately controlled. 4. Optical Imaging System: The camera uses a high-resolution, high-frame-rate progressive scan CMOS digital camera, which is particularly suitable for the measurement and analysis of dynamic processes that change at high speeds The lens adopts a large depth of field lens with continuously variable magnification, low distortion rate and superior parfocal performance The backlight adopts a continuously adjustable brightness LED cold light source, which has long service life and even light emission, providing a background lighting condition for clear imaging. 5. Professional analysis software: Provides various methods such as volume angle method, volume high method, fitting method, automatic method, hanging drop method, insert plate method and bubble trap method Add the appropriate option to test the contact angle between the liquid's static/static contact angle and the external phase immiscible liquid on the solid surface The left and right contact angles can be tested and compared separately. The software automatically calculates the average contact angle. With surface correction function for testing contact angles of convex and concave surfaces, spherical surfaces, and rough irregular surfaces The picture can be directly measured without saving, any three-point circle can be used to find the contact angle value, and the contact angle value can also be automatically analyzed. Not only can the liquid surface/boundary tension be measured, but also the droplet's outline size can be calculated, and the critical micelle concentration of the surfactant can also be analyzed. Provides a variety of surface free energy estimation models for polar, non-polar, low energy, high energy, etc. solid surfaces Provides single shooting, interval shooting and continuous shooting in 3 shooting modes to record and analyze changes in contact angle at different time periods Provide video shooting function, can be saved in AVI format for process observation or PPT file production Features such as coordinate display, brightness adjustment, baseline assistance, and fast memory auto-trigger help analyze images accurately and clearly With powerful database management capabilities, saving, printing, raw data query, and re-analysis can be implemented
