KRÜSS DSA25S Drop Shape Analyzer

Manufacturer: KRÜSS 
Model: DSA25S 

The KRÜSS model DSA25S Drop Shape Analyzer is a high-precision instrument designed formeasuring of contact angle (static, advancing & receding, dynamic) of water or other liquids on solid surfaces in air or of air on surfaces underwater; measuring of surface free energy of solid surfaces; measuring of liquid sliding angle on solid surfaces
the shape and contact angle of drops and bubbles. It is used in research and development, quality control, and production monitoring in a wide range of industries such as pharmaceuticals, cosmetics, food, and materials science.

The DSA25S features a high-resolution camera, a high-precision syringe pump, and an advanced software package that enables automated measurements and analysis of contact angles, drop volumes, and surface energies. The instrument can measure contact angles from 0 to 180 degrees and drop volumes from 0.5 to 2,000 µL. The DSA25S comes with a range of accessories such as syringes, needles, and sample holders to accommodate different types of samples and applications. The instrument can be used with a variety of liquids including water, oils, and surfactant solutions.
