Surface tension measurement by pendant drop shape method

Original language description

Surface tension is an important physical property of pure liquid solvents and their mixtures. Pendant drop shape analysis is a classical method developed in 19th century by Bashforth and Adams. The method is based on numerical integration of Laplace ? Young equation. Quick, comfortable and user friendly utilization of this method is nowadays allowed by progress of computer technologies and digital photography. Therefore an apparatus of own design for pendant drop shape method has been built and the final setup is shown in this work. Pendant drop is formed on the tip of stainless steel capillary, constant temperature is ensured by a thermostatic glass cell. A vessel with a studied liquid is placed into the cell under the drop to reach full vapor saturation. Drop image (Fig. 1) is taken by digital camera through a microscope, the source of cold light is used to illuminate the drop. Photography of pendant drop is transferred to the computer and analyzed by FTA software. The apparatus has
