Drop Shape Analyzer DSA25S (KRÜSS)

Contact angle is useful for analysing the wettability of solid substrates, a very simple technique that can provide quick information about the nature of a surface (both chemical and morphological).

The DSA25S, thanks to its versatility, offers the possibility of obtaining other interesting information about materials (solids and liquids) beyond wettability.

Applications:

• Static and dynamic contact angle
• Surface free energy of solids.
• Surface and interfacial tension of liquids.
• Advancing and receding contact angles and evaluation of a roll off angle by tilting table method.

The DSA25S features a high speed camera with a resolution of, at least, 1920 x 1200 px, and an automatic software-controlled dispenser and tilting stage.
