The Drop Shape Analyzer
The Krüss DSA 100S Drop Shape Analyzer will analyze the shape of a drop of liquid on a surface, or suspended from a needle, in order to calculate the contact angle, or the surface tension, respectively. It is mostly used to determine the contact angle of water as a measure of the hydrophobicity/hydrophilicity of the sample surface.
The user manual, user APV(s), technical information, and contact information can be found in LabManager:
