Hare’s Apparatus

Product Code : SCL-EAST-14576

Indian Lab Suppliers supplies the Hare’s Apparatus (Product ID: 14576) as part of its elasticity and surface tension range. It compares the densities of two liquids from the heights of the columns they form under the same suction.

Quick Answer

Hare’s apparatus is an inverted U-shaped (or three-limbed) glass tube whose two long limbs dip into beakers of the two liquids. Air is drawn out through the top connection so both liquids rise, and because the reduced pressure is the same for both, h1ρ1 = h2ρ2; the ratio of the column heights gives the ratio of the densities. Please confirm the tube form, scale length and included tubing at quotation. Handle the glass with care.

Where This Is Used

Used for relative-density practicals with liquids that do not mix. The Hare Apparatus (Product ID: 10860) is a stand-mounted version with a 45 cm scale. Browse the full Elasticity and Surface Tension range or related Properties of Matter products.

Frequently Asked Questions

What does Hare’s apparatus measure?
The ratio of the densities of two liquids.

Why do the columns reach different heights?
The same pressure difference supports a shorter column of the denser liquid.

What is needed to operate it?
Only gentle suction at the top connection, for example from a rubber bulb or small hand pump, and a pinch clip to hold the columns.
