Drop Shape Analyzer – DSA30 Contact angle measurement in quality control Our Drop Shape Analyzer – DSA30 is a robust instrument which can be used flexibly for the precise measurement of contact angle and surface free energy (SFE). With high-quality components and various automation options, the DSA30 analyses wetting and adhesion on solid surfaces. Fast measurements and simple operation make the instrument a valuable part of your routine quality control. Solutions for reliable surface investigations We have equipped the DSA30 with a uniform LED lighting unit, high-quality optical components and a high-resolution camera. This results in a precise image of the dispensed drop which ensures that the drop shape can be reliably evaluated for the contact angle. An aperture on the lighting unit provides optimum optical conditions for small contact angles and reflective samples, which otherwise often present a challenge when measuring the contact angle. Our finely adjustable sample table moves the sample quickly and reproducibly to the measuring positions with up to three manual or automatic axes. Dosing units for up to four liquids enable the surface free energy of solid samples to be measured with high accuracy. Our pressurized double-dosing unit allows measuring the SFE extremely fast and reliable, using our novel, scientifically validated dosing technique, the Liquid Needle.
