The droplet shape analyzer - DSA30 is a flexible and accurate instrument for measuring contact angle and surface free energy. With its excellent product quality and abundant optional automation accessories, as well as its fast and easy operation characteristics, DSA30 has become a necessary instrument for daily QC testing of solid surface wettability and adhesion properties.
measuring method
Measure the contact angle between liquid and solid
Analyze the surface using all common models based on the contact angle between the solid and several testing fluids
free energy
Static contact angle, forward and backward angles
Measurement of surface tension and liquid-liquid interface tension (using suspension drop method)
Measure inclination angle
Realize constant temperature measurement within the range of -30 to 400 ° C
Measure at preset humidity
Rheological analysis of interfaces (elasticity, viscosity)
