Surface Characterization
Surface characterization equipment | Substrates and fabrication | Resources | Technical Support
Accurate and reliable surface characterization is essential across many applications. In coatings, it is important to characterize the properties of new materials (sometimes in both liquid and solid form depending on the application), evalute surface modification, or optimize adhesion and wettability. For electrical characterization of thin films, wafers, and materials, sheet resistance measurements, made simple with a four-point probe system, are critical.
Choose surface characterization equipment from Ossila to equip your lab ready for high performance analysis at an accessible price.

Quickly measure sheet resistance, resistivity, and conductivity of your thin films right on your lab bench, even when you have no access to a PC.
For sheet resistance measurements, simply load in your sample and press go. Inputting the sample dimensions enables the system to also measure conductivity and resistivity while outputting real-time data of current and voltage between the outer pins and the voltage between the inner pins.
As with the Original model, the Four-Point Probe Plus is available with your choice of soft-tipped or sharp-tipped probes to suit your samples.
For efficient ink and coating optimization, choose the Ossila Contact Angle Goniometer. The affordable system equips your lab with intuitive PC software, high quality video, and rapid image capture.
The high-resolution camera captures up to 30 frames per second and the manual focusing lens gives you full control over image sharpness. Using the monochromatic backlight, the software accurately detects the droplet edge. With two modes, the complete software is capable of recording and analysis, both surface tension and contact, for full characterization.

Contact Angle Measurements on Uneven Surfaces
A sloped surface is usually just any flat surface at an angle. This has a linear gradient and can be flattened by adjusting the tilt of the sample stage, or rotating the video or image in the software included with the Ossila Contact Angle Goniometer.
