Descriptions of Surface Tension Apparatus
For determination of surface tension of liquids. Comprises a metal bridge attached to a vertical rod, which in turn is mounted on pillar of a heavy cast metal stand adjustable for height and has leveling screws. Across the two arms of Ushaped bridge, a steel torsion wire is fixed with provision for adjusting its torsion. A pan is hung from a notch in the pointer and has a hook at its underside from which can be suspended a light weight rectangular frame or a metal clip to hold a micro slide edge. The tip of the pointer moves over a graduated scale mounted vertically on the end of arm fitted to the bridge. With rectangular wire frame, slide clip, six micro slides and spare length of torsion wire. The sensitivity of the balance depends on the modulus of elasticity of the torsion wire. Wire of different diameter will provide different sensitivities.

Easy Cleaning and MaintenanceThe apparatus can be quickly disassembled, making it straightforward to clean the beaker and ring after experiments. This ensures reliable performance and minimizes contamination between usage.
FAQs of Surface Tension Apparatus:
Q: How does the Surface Tension Apparatus measure liquid surface tension?
A: It uses the du Nouy ring method, where a platinum/iridium ring is carefully lowered into and lifted from a liquid in the provided glass beaker. The force required to detach the ring is measured using the analog scale, which accurately reflects the surface tension of the liquid.
Q: What is the capacity range of the supplied beaker, and what liquids can be tested?
A: The apparatus is supplied with a glass beaker of 250500 ml capacity, suitable for most laboratory liquids. It can measure the surface tension of a broad range of water-based and other chemical solutions, as long as they are compatible with the apparatus materials.
Q: When and where is the apparatus ideally used?
A: This apparatus is best utilized during laboratory experiments in physics or chemistry settings. It is designed for ambient laboratory temperatures between approximately 15C and 40C, making it ideal for standard educational or research labs.
Q: What is the process for adjusting the ring position during measurement?
A: The vertical adjustment feature allows smooth and precise raising or lowering of the platinum/iridium ring. This ensures the ring is correctly positioned for each test, enabling accurate and reproducible results.
Q: How do you clean and maintain the Surface Tension Apparatus?
A: The apparatus is engineered to be easy to disassemble. After use, you should remove the glass beaker and ring, clean them with appropriate laboratory cleaning agents, and let them dry before reassembling for the next experiment.
Q: What are the main benefits of using this apparatus for surface tension experiments?
A: It offers 100% accuracy, high efficiency in measurements, and longevity due to corrosion-resistant finishes. Manual operation assures flexibility, and analog scale readings are simple yet highly reliable for scientific documentation.
