The versatile manual instrument for changing contact angle tasks
In its Basic version, the DSA30 Drop Shape Analyzer specializes in the accurate wetting measurement by means of the static contact angle. With fast and simple exchange of solid samples and dosing liquids, the instrument assists you in ensuring the effectiveness of cleaning procedures or the quality of coating and wetting processes. Optional accessories for wetting measurements at higher temperatures and manifold upgrade options enhance the spectrum of the instrument.
