In this article, a simple and low-cost device is designed and fabricated for measuring the surface tension of blood by pendant drop method. In this device, a droplet of blood is formed in a closed chamber on tip of an 18-gauge blunt needle and it is photographed by a camera in very ...
In this study, we examine the accuracy of measuring the surface tension of glass melts using the sessile or pendant drop methods. Experimental data show that the accuracy of surface tension measurement using the pendant drop method (±3 mN/m) is better than that obtained by using the sessile...

Based on the pendant drop method, an optical (graphical)-numerical procedure was developed to determine surface tension and its dependency on the surrounding temperature. For modeling and experimental verification, chemically inert and thermally stable perfluorocarbon (PFC) oil and water was used. ...

The electron bombardment/pendant drop technique for determination of values of surface tension of liquid metals is described and the basic physical disadvantages are enumerated. The method is recommended only for reactive and high melting point metals and then only where other methods have proved inappl...
A quasi-containerles pendant drop method for measuring the surface tension of molten metals and alloys is being developed. The technique involves melting the end of a high-purity metal rod by bombardment with an electron beam to form a pendant drop under ultra-high-vacuum conditions to minimize...

Method and Device for handling drops comprising at least have a drop in contact with a fixed bracket of a subject area drops,Generate an electric field in the area, to move the drop under the effect of the Clamping Force, the area is aligned such that a normal Surface form an angle less...
The surface tension values obtained from this method were found to be in good agreement with results obtained using the standard pendant drop technique. Damping of capillary waves on pendant drops was shown to be similar to that observed for deep liquid baths and the kinematic viscosities obtained...
