Measuring surface free energy in a second with only one click

The innovative Mobile Surface Analyzer - MSA measures surface free energy with two liquids, fully automatically and mobile using a new "One-Click SFE" method. The MSA doses two parallel drops with one click, followed by the direct analysis of the contact angles and the derived results of the surface free energy. All steps are automated and happen within a second. The results enable well-founded statements about wettability by aqueous or organic liquids. The MSA supports you in your quality assurance in the pre-treatment and coating of solid materials in an ideal way.

New innovative dosing unit for parallel analysis with two test liquids
The specially developed double dosing system doses two parallel drops within milliseconds, with high volume precision and minimal kinetic energy. This simultaneous dosing of two drops obviates the need to change the test liquid during the material analysis, as is the case with conventional dosing units. The contactless method prevents unwanted touching of the sample with possible contamination or damage.

Cartridges that can easily be refilled outside the instrument make for simple operation of the dosing system. Fully charged, the handy instrument is capable of dosing 1,000 droplets of each liquid.

Krüss has developed an alternative dosing solution which uses conventional disposable syringes for liquids that require extensive cleaning effort such as adhesives, inks or paints. The conversion to this automatic syringe dosing module is done very quickly.
