Contact angle measuring device - DSA30 series
The Drop Shape Analyzer series DSA30 is a robust instrument which can be used flexibly for the precise measurement of contact angle and surface free energy. 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 everyday quality control.The DSA30 comprises of a uniform 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.
