The MobileDrop from KRÜSS has achieved a new dimension in mobility and simplicity for the contact angle measuring technique. The measuring head only weighs 500 g and can be comfortably operated with only one hand.

The compact space within the housing is occupied by high-precision components: prism optics, an “intelligent” camera and a fast exchangeable dosing unit.
Operation with a notebook ensures fully independent on-site use of the instrument.
The ergonomic measuring head is placed on the sample, which can be of almost any size. The dosing lever lowers the needle and deposits the liquid – the drop volume can be adjusted in 2 µl steps.
A prism arrangement transfers the outline shape of the drop via the builtin camera to the connected notebook, where the time-proven KRÜSS SW23 (DSA2) software evaluates the drop video.

A range of different liquids can be deposited in quick succession - the DSA2 uses the drop shapes to determine the contact angle and then calculates the surface free energy from it. KRÜSS has incorporated the most important evaluation techniques for contact angles and SFE in the software.
A comprehensive substance database and comfortable data management round off the program.
