Goniometer surface tension

WebMeasurement of surface tension can be performed with a force tensiometer. These instruments are based on measuring the forces exerted on a probe that is positioned at the liquid-gas or liquid-liquid interface. The probe is connected to a very sensitive balance and the liquid interface of interest is brought into contact with the probe. WebBrighton Science's Surface Analyst™ is essentially a smart, hand-held goniometer. However, unlike a benchtop goniometer, the Surface Analyst takes measurements vertically--rather than horizontally--using a patented process called Ballistic Deposition. The instrument deposits a stream of micro-drops that coalesce on the surface.
