Contact Angle Goniometer Features
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.
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
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
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.

Testimonials
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.

Software
The Contact Angle Goniometer comes complete with user-friendly measurement software. This software has been designed to be as intuitive as possible, but we also provide guides on how to use it effectively. The software has two main interactive sections: recording and analysis.
The Ossila Contact Angle software is included on the supplied USB memory stick, and the latest version is always available to download for free from our website.
Recording
Capture high-resolution videos in the recording section of the software. The videos will automatically be saved to the destination of your choosing and are saved in .avi file format, which means you can watch them in any common video player or edit them in a video editor. When loaded into the contact angle software, the videos will appear as a series of images which can be analysed individually.
Analysis
Measure contact angle and surface tension of your recorded droplets in the analysis section of the software. The software performs an edge detection algorithm on the droplet, then uses an appropriate fitting technique to calculate its properties.
Contact Angle
For droplets with contact angles above 10°, a polynomial curve is fitted to the droplet edge. Where the curve crosses the baseline, its tangent is used to determine the contact angle. If a droplet is below 10°, then a circle fit is used for contact angle measurements instead.
Surface Tension
The software can also perform optical tensiometry measurements on droplets suspended from a needle tip. A series of droplet models are created using the droplet radius and liquid density. The models are compared with the detected edge and the closest match is used to determine the surface tension of the liquid.
