Automatic wettability analysis of large surfaces
The Large version of the DSA100 Drop Shape Analyzer is prepared for automated wettability analysis by means of the contact angle or even the surface free energy. Fitted in a particularly wide frame and equipped with a large, rotating sample table plus an extra-long movement axis, the instrument can handle samples of an area of up to 500 × 500 mm.
