Wetting behaviour

At the TITK, investigations can be carried out on the wetting behaviour of surfaces, the determination of contact angle, roll-off angle, polar and disperse components of the surface energy as well as other characteristic features of interfaces and surfaces.

• Measurement on hanging drop (pendant drop)
• Measurement on a sitting drop (sessile drop)
• Measurement on curved surfaces (roll-off angle)
• Measurements under inert gas atmosphere are possible

• Measuring device: DSA100 (Krüss)
• PC-controlled single and multi-dosing system (4 different test liquids)
• Special liquids possible
• Integrated camera (up to 360 images/s)
• Peltier temperature chamber (-30 °C to 160 °C)
• Inert gas connection
• Tilting table
