DSA100E

The automated premium solution for wetting and adhesion analysis of solids and liquids

The Expert version of the DSA100 Drop Shape Analyzer system solution enables solids and liquids in wetting and coating processes to be analyzed comprehensively. The high degree of automation with easy programmable procedures provides for user-independent contact angle and surface tension results, which is ideal for the use in quality control. However, the DSA100E is also frequently used in R&D due to its versatility in controlling thermal conditions, its multi-dosing option with up to eight test liquids, and its scientific tools for analyzing the solid/liquid contact.

Specifications:

• Contact angle between a liquid and a solid

• Surface free energy from contact angles of several test liquids using all common models

• Static, advancing and receding contact angle

• Roll-off angle on hydrophobic and superhydrophobic surfaces

• Measurement of surface tension and liquid-liquid interfacial tension using the Pendant Drop method

• Temperature-controlled measurements from -30 to 400 °C

• Measurements under controlled humidity

• Wetting measurements on microscopically small surfaces Interfacial rheology measurements
