The DSA30 is one of our helpful tools in developing sustainable plastic solutions for the future.
Drop Shape Analyzer
DSA30B
The versatile manual instrument for changing contact angle tasks
In its Basic version, the DSA30 Drop Shape Analyzer specializes in the accurate wetting measurement by means of the static contact angle. With fast and simple exchange of solid samples and dosing liquids, the instrument assists you in ensuring the effectiveness of cleaning procedures or the quality of coating and wetting processes. Optional accessories for wetting measurements at higher temperatures and manifold upgrade options enhance the spectrum of the instrument.
Applications
-
Analyzing the wettability of plastics, glass, ceramics, wood, paper, or metal
-
Analyzing the effectiveness of hydrophobic coatings and other coatings
-
Analyzing surface cleanliness
-
Wetting analysis at controlled temperature
Measuring methods
-
Contact angle of a drop on a solid surface

-
Surface tension using the curvature of a perfectly symmetrical drop on a circular sample pedestal
-
Roll-off behavior and advancing/receding contact angle of a drop on a tilted surface
-
Contact angle at an immersed, cylindrical sample, usually a fiber
-
Measuring the recently receded contact angle to characterize dewetting behavior

Manual precision dosing for quick changes of liquids
Thanks to the fine adjustment of the manual dosing unit of the DSA30B, the drop is dispensed in an accurately controlled manner. The size of the drop is therefore highly reproducible and provides a good comparison of results. The quickly replaceable syringe allows a rapid changeover between different liquids, thus enabling a high sample throughput.
Reliable drop shape analysis thanks to high imaging quality
The DSA30B features a high-resolution camera and a quality zoom lens for accurate display of the drop with optimum size. The high image quality that this achieves leads to a precisely measured contact angle. Combined with the intelligent image evaluation algorithm of the ADVANCE software, drop shape analysis with the instrument provides exact results.
Many accessories and upgrade options
In addition to extensive accessories, e.g. for temperature control, we provide extensive upgrade options for the DSA30B to the Standard (S) and Expert (E) unit configurations. These offer you software-controlled drop dosing of up to four liquids as well as manual or even automated horizontal and vertical sample positioning.
Dosing automation at the highest level
Equip your instrument with the optional Dosing Hub, our flexible positioning and changing system for up to three combinable dosing units. Together with software-controlled dosing solutions, the system performs automatic and fast surface free energy measurements with up to four liquids, for example. The Dosing Hub also integrates temperature-controlled dosing units and other special solutions.
