Drop Shape Analyzer

The easy-to-use manual instrument for changing contact angle tasks

The Basic configuration of the DSA25 Drop Shape Analyzer is suitable for accurate wetting measurements with a standard test liquid or sample liquid. The instrument is ideal for quick measurements of the static contact angle. It is mainly used for tasks that don’t require a high degree of standardization, i.e. wetting of different formulations of a coating liquid on different samples.

Specifications:

• Contact angle between a liquid and a solid

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

• Static contact angle, advancing angle and receding angle

• 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
