Hare’s apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12730
The Hare’s Apparatus by Educational Instrument India is a useful physics laboratory instrument designed to compare the densities of two liquids using the principle of hydrostatic pressure. It is commonly used in school laboratories, college physics labs, and educational institutions for practical experiments related to liquid density, pressure, and specific gravity.
This apparatus generally consists of two vertical glass tubes connected at the top with a suction arrangement. The lower ends of the tubes are dipped into two different liquids. When air is partially removed from the tubes, the liquids rise to different heights. By measuring the height of the liquid columns, students can compare the densities of the liquids.
Hare’s Apparatus provides a simple and effective way to demonstrate how liquid density affects the height of a liquid column under the same pressure difference. It is ideal for student practicals, classroom demonstrations, and physics experiments related to fluid mechanics.
