NanoFab Tool: First Ten Angstroms FTA125 Contact Angle Goniometer
Photograph of the First Ten Angstroms FTA125 general purpose goniometer.
The First Ten Angstroms FTA125 is a general purpose goniometer that can measure the contact angle and surface tension of liquid droplets on a substrate's surface. The FTA125 provides automatic video based measurements on substrates ranging from 150 mm diameter wafers down to small pieces.
Specifications/Capabilities
- Droplet volumes: 3 µL to 15 µL.
- Contact angles measured: 0° to 180°.
- Surface tension measurements using pendant drop shape analysis.
Usage Information
Supported Sample Sizes
- Maximum wafer diameter: 150 mm (6 in).
- Small pieces supported: Yes.
- Maximum thickness: 2 mm.
Typical Applications
- Measurement of the contact angle between a liquid droplet and a substrate surface.
- Surface tension calculation.
- Liquid droplet shape analysis.
