Hare Apparatus
Product Code : LSK-POM-11184
Hare Apparatus (SKU LSK-POM-11184), also called Hare's tube, compares the densities of two liquids: suction on the short limb of a three-limbed tube draws both liquids up, and the heights of the two columns are read on a 45 cm scale. It is a standard Class 11 physics and college hydrostatics practical. Science Lab Supplies mounts the apparatus on a polished stand at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, quoting schools, colleges, tender contractors and distributors without intermediaries.
Specifications
The table lists each specification of the Hare apparatus. In summary, a three-limbed tube is mounted on a polished stand beside a 45 cm metre scale with zero at the bottom, divided in centimetres and millimetres; suction is applied through the short limb, and rubber tube and pinch cock are not supplied.

Applications and Experiments for the Hare Apparatus
The Hare apparatus finds the relative density of a liquid by balancing two liquid columns against the same reduced pressure, so the ratio of their heights equals the inverse ratio of their densities. It is used in Class 11 physics and in B.Sc. and diploma hydrostatics practicals.
- Class 11 physics: relative density of a salt solution, oil or spirit against water, with suction applied through Rubber Tube (Laboratory) on the short limb.
- Holding the columns steady while reading by closing the tubing with a Screw Pipe Clamp (Hoffman Clamp) or an Elastic Clamp for Rubber Pipes (Mohr Clamp).
- Plotting one column height against the other for several suctions to obtain relative density from the slope.
- Demonstrating that liquid pressure depends on depth and density.
Standard Scope of Supply
The supply covers the three-limbed tube mounted on the polished stand with its 45 cm scale. It is supplied without rubber tube and pinch cock, which can be added to the quotation; a spare three-limbed tube is also available on demand.
Packing, MOQ and Lead Time
A quotation can list a single Hare apparatus, a class quantity, or extra spare tubes for breakage cover. Science Lab Supplies sets out packing, delivery time and price for the numbers you give, and rubber tubing or pinch clamps can be added on the same quotation.
With its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda.

Frequently Asked Questions
Are the rubber tube and pinch cock included?
No. The apparatus is supplied without rubber tube and pinch cock. Both can be quoted alongside it, so the set arrives ready to use for suction and holding the columns.
How is the scale arranged?
The metre scale is 45 cm long with zero at the bottom and is divided in centimetres and millimetres, so both column heights are read from the same base level.
Can a replacement tube be ordered?
Yes. A spare three-limbed tube is available on demand. It can be added to the original quotation or ordered later to replace a broken tube on the same stand.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the maker. The tube is mounted on its stand and scale at the company's Saha, Ambala factory in India, and quotations are prepared there for every buyer.
