Drop Shape Analyzer

The manual premium solution for changing contact angle tasks

The Basic configuration of the DSA100 Drop Shape Analyzer combines manual precision measurement of the static contact angle with the technical advantages and robustness of the DSA100 system solution. 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 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
• Contact angle using a gas bubble beneath a solid surface in a liquid
• Roll-off behavior and advancing/receding contact angle of a drop on a tilted surface
• Surface tension using the curvature of a perfectly symmetrical drop on a circular sample pedestal
• Contact angle at an immersed, cylindrical sample, usually a fiber
• Measuring the recently receded contact angle to characterize dewetting behavior

Measuring results

• Static contact angle

• Contact angle using a bubble in a liquid

• Temperature
