Drop Shape Analyzer (DSA100, Krüss)
DSA100 drop shape analyzer (Krüss) could perform both static and dynamic contact angle, surface/interfacial tension, and surface free energy measurements with a software-controlled dosing system and a tilt stage.
First Ten Angstroms FTÅ 125 Contact Angle/Surface Tension Analyzer
Measures both contact angles and surface tensions. Surface energy can also be calculated based on those measurements. Standard pipette syringes dispense fluid and the stage is raised by a rack-and-pinion lift. Allows for a specimen up to 250mm wide.
