Drop Shape Analyzer – DSA25S – Krüss

The Krüss DSA25S Drop Shape Analyzer specializes in measuring static or dynamic contact angles, and calculating surface free energy from these measurements. It is ideal for evaluating the wettability of various surfaces, making it an indispensable tool for confirming the efficacy of cleaning, pretreatment, or coating processes.

Yes, the Krüss DSA25S is highly versatile and can be applied to a wide array of materials including plastics, glass, ceramics, wood, paper, and metals. This makes it suitable for a broad spectrum of applications, from checking the wettability of hydrophobic coatings to conducting wetting analysis under controlled temperatures.

The accuracy and reliability of the DSA25S are achieved through its high-resolution camera and premium optics. Enhanced measurement capabilities are further supported by the ADVANCE software, facilitating efficient data processing and enabling time-controlled measurements for analyzing time-sensitive wetting behaviors.

The DSA25S employs a syringe dosing system with optional liquid needle double pressure dosing. It includes manual drop deposition and offers a dosing speed ranging from 0.004 to 25 µL/s, with a resolution of 20 nL. This provides precise control over the liquid dosing necessary for accurate surface analysis.

Yes, temperature control is an optional feature that can be added to the DSA25S Analyzer. It includes options for a temperature-controlled sample stage, chamber, and cuvette, with a broad temperature control range across various equipment options, such as liquid, Peltier, and electrical, accommodating a wide range of experimental needs.

Absolutely. The DSA25S Analyzer, especially when equipped with an optional extender lens, is capable of measuring contact angles on fibers or small samples. It offers specific modules for capturing static and dynamic contact angles on minimum fiber diameters down to 40 μm with enhanced resolution, providing detailed analysis for nearly any size sample.

The optional high-speed camera, model CF10, increases the Analyzer's frame rate to 3450 fps and offers a higher resolution of 2592 × 2048 px. This enhancement allows for a more detailed and rapid capture of dynamic wetting processes, making the DSA25S suitable for complex and fast-moving surface analysis applications.
