Contact angle – surface free energy – surface tension - roughness: the DSA30 offers numerous possibilities at a competitive price. The modular system provides a wide range of high-performance solutions for studying the surfaces of solids. The contact angle measuring instrument is ideal for QA material testing of medium sized samples at standard measuring throughputs. A large selection of basic components and accessories offers a solution for almost any measuring problem.

• High-performance contact angle measuring instrument at a favourable price
• Modular measuring system, can be extended at any time
• High degree of automation possible
• Static or dynamic contact angle measurements
• High-temperature measurements and measurements at controlled relative humidity

Answers to a lot of questions

Each drop tells a story. The shape that it assumes on a solid surface reveals its wettability and surface free energy; its degree of adhesion or the roughness of the surface The DSA30 makes the drops talk.

Coatings: Each coating process requires a suitable substrate surface energy value which is in turn modified by the coating process. Contact angle measurements help to measure such values and to adjust them as required.

Cleaning: The contact angle value is very sensitive to surface contamination. It clearly reveals the quality of a cleaning process.

Adhesion: Adhesion is the bond created between surfaces The contact angle gives information about the strength and stability of this bond.

Wetting: Sometimes a liquid should completely wet a surface, sometimes not at all or as little as possible. In both cases contact angle measurement is the answer.

Research: How polar is a surface? Do hydrogen bonds play a role? How do roughness and the chemical structure affect the wetting process? The contact angle provides the answers to such questions.

Modules provide a lot of scope

The one thing that you will always commit yourself to is quality. The DSA30 is an extendable modular system that can be adapted to meet your requirements. Starting from a simple basic version for occasional measurements, or the standard model and right up to an expert instrument for complex and extensive measuring tasks, the DSA30 tailors to your needs.

• Optics with manual or software-controlled zoom
• One to three axes, manually or software-controlled
• Manual or motor-driven single dosing system - or a 4-fold dosing system for automatic liquid selection
• Standard or high-speed camera
• Modular software in basic, standard or expert versions
