Drop Shape Analyzer – DSA25 The precision basic instrument for wetting investigations Our Drop Shape Analyzer – DSA25 is an easy-to-use, reliable instrument for measuring contact angle. From a simple wetting test to the accurate measurement of surface free energy (SFE), the robust instrument provides flexible options for analyzing wetting and adhesion on solid surfaces. Its rapid, manual operation makes our DSA25 outstandingly suitable for occasional wetting measurements with changing tasks and sample types. Well-conceived details for reliable measurement The uniform lighting and high-quality optical components ensure that the dispensed drop is portrayed with the correct shape, and that the contact angle is measured reliably. The sample is quickly moved to the required measuring height using our finely adjustable lift table. The table can be easily moved and the required dosing position quickly set thanks to the magnetic fixing. With dosing units for one or two liquids, the instrument is suitably equipped for simple wetting tests or for measuring surface free energy. With the software-controlled variant, the dosing dynamics can be accurately adjusted in order to make exact measurements of advancing and receding angles. As an alternative, our pressurized double-dosing unit allows measuring the SFE extremely fast and reliable, using our novel, scientifically validated dosing technique, the Liquid Needle.
