Capillary Tubes Apparatus
Capillary Tubes Apparatus is a fundamental scientific instrument widely used in physics and fluid mechanics laboratories to study the phenomenon of capillarity and surface tension in liquids. It demonstrates the rise or fall of liquids in narrow tubes due to cohesive and adhesive forces, allowing students and researchers to understand the principles governing fluid behavior at microscopic levels.
The apparatus typically consists of a set of capillary tubes of varying internal diameters, mounted vertically on a stand with a graduated scale for precise measurement. The tubes are made from high-quality, transparent glass to provide clear visibility of the liquid level. The base stand is sturdy and often provided with a small reservoir or trough to hold the test liquid, such as water, alcohol, or mercury (depending on the experiment).
Product Description:-
This apparatus is used to measure surface tension by Capillary rise in a small bore. It comprises six glass capillary tubes 125 mm long, ends ground flat, of different bores, supported by a metal frame in a shallow metal trough. The upper part of the frame supports six capillary tubes, each of a different bore, their lower ends resting in the bottom trough. The trough is filled with water the difference in the heights of the resulting columns of water in the tubes is readily apparent. Overall frame height: 90mm capillary tubes length: 150mm
For demonstrating the relationship between capillary pressure and the bore diameter of the capillary tube.
The Apparatus comprises of a metal frame, the base of which takes the form of a trough 15x40x10 mm.
