Product Description

Product Description
ASTM D5725 ISO 304 Standard Optical Contact Angle Meter Surface Tension Contact Angle Tester Optical Contact Angle Goniometer

Principle Overview:

The contact angle is defined as the angle (θ) formed between the tangent to the gas-liquid interface-drawn at the point where the gas, liquid, and solid phases meet-and the solid-liquid interface, measured on the liquid side; it serves as a measure of the degree of wetting. It is currently a primary method for characterizing surface properties. Utilizing optical imaging principles, the instrument measures parameters such as contact angle, wettability, surface/interfacial tension, advancing and receding angles, and surface energy. It primarily consists of a light source, a dispensing unit, a sample stage, an image acquisition system, and analysis software.

ASTM D724 ISO 4311 Optical Contact Angle Tester Surface Tension Meter Interfacial Tension Tester Wettability Test Machine

Applications:
This instrument is designed to test and analyze the contact angle of liquids on solid surfaces, liquid surface tension, and solid surface energy. It enables the analysis of surface hydrophilicity/hydrophobicity and wettability, as well as cleanliness inspection and the evaluation of surface treatment effects. It also facilitates the study of processes such as liquid competition, adsorption, absorption, and spreading. It is widely used for testing and research across diverse sectors, including the chemical industry, pharmaceuticals, food processing, electronics, printing and dyeing, coating/spraying industry, and scientific research and education.

ASTM D724 ISO 4311 Optical Contact Angle Tester Surface Tension Meter Interfacial Tension Tester Wettability Test Machine

Instrument Features: 
Precision Engineering: The system frame is constructed from high-quality, imported, high-strength aluminum profiles with an oxidation-resistant, baked-enamel finish; all other major components are precision-machined from aluminum alloy, stainless steel, and copper alloy.

Precision Positioning: All linear motion units-including the 3D sample stage (X-Y axes) and the Z-axis adjustment for the syringe/needle-are driven by linear gear racks and precision dovetail slides, ensuring smooth, effortless, and fine-tuned movement.
Automatic Control: The GA-200 comes standard with a professional-grade, software-controlled precision Automatic Dispensing (AD) system. It utilizes precision linear guides for dispensing with an accuracy of 0.1 µL, ensuring measurement precision and repeatability. Departing from traditional tubing-based fluid delivery, the system employs a direct-push plunger mechanism; this facilitates easier cleaning and replacement of syringes while eliminating the difficulties associated with traditional tubing systems-such as the challenge of purging air bubbles and the need for specialized operators. It accommodates high-precision gas-tight glass microsyringes (for applications requiring precise volume control) as well as disposable plastic syringes (for measuring hard-to-clean liquid samples). When the liquid is depleted, the system can be automatically refilled directly from an included 5 mL beaker.

Comprehensive Syringe and Needle Options: A wide range of syringe specifications is available to meet diverse customer needs, including various capacities (25 µL to 1000 µL), materials (gas-tight glass or plastic), and brands (e.g., Hamilton, Boli). A variety of needles are also offered, featuring different gauges (10-34#), materials (stainless steel, PTFE, or flexible PP), and specialized shapes (such as bent needles). These are suitable for standard contact angle measurements as well as specialized applications involving superhydrophobic, superhydrophilic, or high-viscosity liquids, including sample dispensing and droplet transfer. Imaging System: The GA-200 comes standard with a high-resolution CMOS image sensor featuring a rolling shutter and a Pomeas 0.7-4.5x telecentric profile lens, ensuring optimal imaging quality. Additionally, a high-intensity cold-light backlight-with continuously adjustable digital brightness-provides uniform background illumination for imaging.

Leading Software Platform: The software serves as the soul and brain of the entire measurement system. Developed and customized by our company, the software offers a wide range of functions and features, many of which are industry-leading. As an optical measurement method, accuracy depends on image quality and the subsequent processing, analysis, and calculation techniques. Core components of the software include sub-pixel droplet coordinate detection, automatic identification of the liquid-solid-gas three-phase contact line, full-profile droplet analysis, and continuous feedback-based droplet monitoring-all of which operate in real-time.
