The DSA25B Drop Shape Analyzer from Kruss USA is designed for precise wetting measurements, particularly for static contact angles. It features a 5-megapixel high-speed camera with a resolution of 1920 vó 1200 pixels and a frame rate of 2300 fps, allowing for detailed imaging of drop shapes. The device supports manual and software-controlled dosing systems, with syringe options that provide a resolution of 20 nL and dosing speeds from 0.004 to 25 ¬µL/s. The analyzer is equipped with a high-power monochromatic LED light source at a wavelength of 470 nm, ensuring consistent illumination for accurate measurements. It can measure contact angles ranging from 0 to 180¬8 with a resolution of 0.01¬8, and it is capable of determining surface free energy and interfacial tension. The DSA25B is suitable for various applications, including testing the wettability of materials such as plastics, glass, and metals, as well as evaluating the effectiveness of coatings. Its compact design and temperature control capabilities enhance its versatility in laboratory settings.
The Basic configuration of the DSA25 Drop Shape Analyzer is suitable for accurate wetting measurements with a standard test liquid or sample liquid. The instrument is ideal for quick measurements of the static contact angle. It is mainly used for tasks that don’t require a high degree of standardization, i.e. wetting of different formulations of a coating liquid on different samples.
