Mobile Contact Angle Measurement on Samples of Virtually Any Size
Jun 20 2006
MobileDrop is operated with only one hand and permits measurements to be made on surfaces of virtually any size. Despite its small space requirements, a prism optics system ensures a sharp image of the drop contour. Drop deposition with different liquids allows the surface free energy and its polar and dispersive fractions to be determined in a short time. All components are contained in an ergonomic housing together with a USB camera.
The video image is transferred to a notebook which does the mental work: analysis of the drop shape and calculation of contact angles and surface energies with the software DSA2. An extensive substance database and comfortable tools for data administration are included.
