Rapid Measurements with Easy, Accurate Analysis

Optimise inks and coatings efficiently with HD recording and intuitive PC software

Overview | Specifications | Features | Gallery | Software | In the Box | Accessories | Resources and Support

The Ossila Contact Angle Goniometer provides a fast, reliable, and easy method to measure contact angles and surface tensions of liquid droplets. Our systems lets you achieve easier ink optimization with intuitive PC software, high quality video, and rapid image capture. Our software helps you characterize high contact angles for water resistant or protective coatings, or low contact angles for highly uniform solution coatings.

Thanks to the low price and compact size, the Ossila Contact Angle Goniometer is a great choice for any characterization setup.

Contact Angle Goniometer Features

High-Resolution camera

High-Resolution Camera

Take quality videos and images of your droplets. A high-resolution 1920 x 1080 camera captures up to 30 frames per second, while the manual focusing lens gives you complete control over image sharpness. If file size is a concern, you can set a lower resolution or frame rate when exporting to save space on your hard drive.

Monochromatic light source

Light Source for Accurate Edge Detection

The powerful, mains-powered monochromatic backlight helps the software to accurately detect the edges of the droplet using a Canny edge detection algorithm. The bright, uniform rectangular panel creates a larger change in pixel lightness than would otherwise occur, which ensures that a sharp edge can be found.

Syringe clamping mechanism

Syringe Clamping Mechanism

The versatile and adaptable clamp system can be used to secure a wide range of droplet dispensing equipment. Included with the Ossila Contact Angle Goniometer system is a 25µl glass syringe with a removable blunt tip needle, which is ideal for dispensing droplets for both contact angle and surface tension measurements.

Adjustable sample stage

Adjustable Sample Stage

Obtain a level surface and prevent the droplet from moving during deposition. Lower and raise the stage without affecting the level so you can add or remove substrates and then position the platform as close to the needle as possible. The fine level of adjustment even lets you set a slight tilt towards the camera to help align the baseline.

I use a Contact Angle Goniometer and Spin Coater from Ossila, the best tools I have ever used for the application of Perovskite solar cells. I plan to order more devices from the same brand.

Contact Angle Measurements of Surface Wetting

Surface wetting occurs when a droplet spreads out over a surface, such that its contact angle is below 90°. When the droplet spreads out completely, this angle will be 0°, and 'complete wetting' will have occurred.
