NanoFab Tool: First Ten Angstroms FTA125 Contact Angle 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.
Droplet volumes: 3 µL to 15 µL.
Contact angles measured: 0° to 180°.
Surface tension measurements using pendant drop shape analysis.
Supported Sample Sizes
Maximum wafer diameter: 150 mm (6 in).
Small pieces supported: Yes.
Maximum thickness: 2 mm.
Measurement of the contact angle between a liquid droplet and a substrate surface.
