For Contact Angle, Surface Free Energy, Interfacial Tension analysis
DSA25 has basic, standard and expert configurations to suit different wetting investigations and thanks to the combination of speed and versatile evaluation options, the analyses give quick feedback to pretreatment steps in quality control but also allow assessing the resulting adhesion.
In its expert configuration, the interaction between two software-controlled dosing units is the main advantage of the DSA25E. The Liquid Needle dosing technology performs rapid one-click measurements of the surface free energy (SFE) based on contact angles of two liquids. The additional syringe dosing unit can be used to add data for a third liquid to consolidate the SFE result or to measure the surface tension (SFT) of a liquid.
To characterize low wettability , there is added optional tilting table for the DSA25: Analyze (super-) hydrophobic and self-cleaning surfaces automatically by means of the contact angle and roll-off angle.
