The Drop Shape Analyzer

The Krüss DSA 100S Drop Shape Analyzer will analyze the shapes of drops of liquid on a surface or suspended from a needle in order to calculate the contact angle or the surface tension, respectively.

The user manual, user APV(s), technical information, and contact information can be found in LabManager:
