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.

Goniometer/Tensiometer Surface scientists commonly use an optical goniometer/tensiometer to measure the surface tension and interfacial tension of a liquid using the pendant or sessile drop methods. A drop is produced and captured using a CCD camera. The drop profile is subsequently … See more In surface science, a tensiometer is a measuring instrument used to measure the surface tension (γ) of liquids or surfaces. Tensiometers are used in research and development laboratories to determine the surface tension of … See more • Stalagmometric method • Surface tension • Young-Laplace equation See more Media related to Tensiometer (surface tension) at Wikimedia Commons See more WebThe Kruss Easy Drop goniometer is used to measure the contact angle of a droplet in contact with a solid surface. The shallower the contact angle the greater the wettability of the drop. The goniometer utilizes a backlight and a high-resolution camera to examine and photograph a sessile drop which has been dispensed by a precision syringe with … formgroup reset form angular

Contact angle data is collected by placing a droplet of deionized water on the surface and by measuring the angle at the interface of the water and the silicon surface using a goniometer or optical comparator.
