| 1. Large and Customizable Measurement Area | The standard 300 × 300 mm table, expandable up to 1000 × 1000 mm, allows testing of both small samples and large panels, making the system highly adaptable for research and industrial applications. |
|---|---|
| 2. High Positioning Accuracy | With 0.01 mm droplet movement precision, the system ensures accurate drop placement and excellent repeatability, even on complex or structured surfaces. |
| 3. Flexible Liquid Handling | The 1000 µL micro-syringe enables controlled manual dosing and supports a wide range of droplet volumes for both static and dynamic measurements. |
| Comprehensive Surface Analysis | Supporting static and dynamic contact angle methods and equipped with a high-resolution camera, the system provides detailed wettability evaluation and reliable surface energy analysis. |
The Contact Angle Measurement System CA300M is a versatile surface analysis instrument designed to evaluate wettability and surface energy using both static and dynamic contact angle measurement methods. It features a standard 300 × 300 mm sample table, customizable up to 1000 × 1000 mm, allowing the analysis of large or specialized specimens. The system uses a manual dripping method with a 1000 µL micro-syringe and provides precise droplet positioning with 0.01 mm movement accuracy for reliable measurements. Equipped with a high-resolution camera, it delivers sharp droplet imaging for accurate and repeatable surface characterization.
