Product Overview

The KRUSS DSA30 is a robust Drop Shape Analyser which offers the flexibly needed for precise measurement of contact angle and surface free energy. With high-quality components and various automation options, the DSA30 analyses wetting and adhesion on solid surfaces. Fast measurements and simple operation make the instrument a valuable part of quality control.

Reliable drop shape analysis with high imaging quality
A high-resolution camera combined with a high-quality zoom lens ensure an accurate determination of the drop with optimal size which leads to a precisely measured contact angle or surface tension (SFT).

Analysing solids with up to four liquids
The DSA30E is equipped with the Dosing Hub for fast positioning and control of the dosing units. It combines the automatic Liquid Needle for fast and gentle dosing and allows automatic, fast, reliable surface free energy measurements with upto four liquids. Alternatively, the DSA30E works together with a multi-dosing system with four syringes.

Automated positioning for complete sample analyses
The DSA30E is fitted with three software-controlled axes that can move the sample quickly and accurately to all programmed measuring positions. This makes it possible to complete standardised analyses, which is ideal for quality control. Wetting can be analysed on the sample position to check for homogeneity or to assess differences between coated and uncoated areas.

Maximum repeatability and comprehensive adhesion analysis
ADVANCE software easy-to-create automation programs can design standard procedures for fully automated sample analyses in no time at all. Optional software tools for data analysis combine SFE and SFT data in order to assess the adhesion and other parameters of the solid/liquid contact.
