How Does It Compare with Other JLab Hare’s Apparatus?
| Model | Stand | Height reading | Other listed details |
|---|---|---|---|
| This apparatus (EL-SLE-4576) | Stand (material not listed) | Not listed | Three-limbed glass tubes; rubber tube and pinch cock included |
| Hare Apparatus | Polished wooden stand | Metre rule on the stand | Suction applied to the short limb |
| Hare’s Apparatus | Wooden stand | A scale for each of the two tubes, plus two sliding distance rods | Three-limbed glass tube; rubber tube with clip on the short centre limb |
Choose this model when you want the basic apparatus with its rubber tube and pinch cock and will measure the column heights yourself. The other two listings add a built-in metre rule or scales, and the second of them also has sliding distance rods that make the readings quicker for a class.
What Is Hare’s Apparatus Used For?
Hare’s apparatus finds the relative density of a liquid without weighing it. The two outer limbs dip into two beakers, one holding water and the other the test liquid, and gentle suction at the third limb lowers the air pressure above both columns by the same amount. Each liquid rises until the weight of its column balances that pressure difference, so column height multiplied by density comes out the same for both liquids, and the relative density of the test liquid equals the height of the water column divided by the height of the liquid column. It is a standard experiment on fluid pressure and relative density in secondary school and pre-university physics, which makes it a useful item among physics lab instruments in India and abroad.
In use, draw the liquids up a little, close the pinch cock on the rubber tube to hold the columns steady, and measure each height from the free surface of the liquid in its beaker to the top of its column. Repeat at several heights and average the ratios. Because the two liquids never touch, liquids that mix or react can still be compared. When the test liquid is anything other than water, apply suction with a rubber bulb or syringe rather than by mouth, and rinse and drain the tubes after each liquid.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; many labs plan one apparatus per group of students.
- Height scale — no scale is listed for this model, so state whether you need one; the linked Hare’s apparatus models are listed with a metre rule or scales.
- Spares — extra rubber tubing and tube clips if you expect wear over several terms.
- Beakers and test liquids — these are separate items and can be added to the same enquiry.
Frequently Asked Questions
What is Hare’s apparatus used for?
It compares the densities of two liquids, usually water and a test liquid, by comparing the heights to which each rises when the same suction is applied to both.
How is the relative density worked out?
Both columns are held up by the same pressure difference, so height times density is equal for the two liquids. The relative density of the test liquid is therefore the water column height divided by the test-liquid column height.
Which accessories are included?
The rubber tube and the pinch cock are included with the apparatus on its stand. Beakers and the liquids to be tested are not part of this listing.
Does this model have a scale for reading the heights?
A scale is not listed for this model, so heights can be measured with a separate metre rule, or you can ask JLab to confirm a scale on your order. The two linked Hare’s apparatus listings have a metre rule or a scale on the stand.
Can it compare liquids that mix or react with each other?
Yes. Each liquid stays in its own beaker and its own limb, with air between them in the connecting tube, so the liquids never come into contact.
What is the minimum order and dispatch lead time?
The minimum order is 10 units, supplied individually. Orders usually ship within 7–10 working days, every apparatus is visually inspected before it leaves the works, and transit time for export orders depends on the destination.
What should an export enquiry include?
The quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling requirements and, for a tender, its reference number.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd (JLab) manufactures it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and general science lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This apparatus is assembled at JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers buy it factory-direct; each one is inspected by eye before dispatch, and spares and repeat orders are dealt with by the manufacturer. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. It exports worldwide and can ship to buyers in every region, for example Tajikistan in Central Asia, Nepal in South Asia, Austria in Western Europe, Bahrain in the Middle East and Bolivia in South America. Tender buyers can refer to the JLab lab tenders page.
Other Density and Fluid Apparatus
- Specific Gravity Bottle — a spherical borosilicate glass bottle with stopper, for finding relative density by weighing.
- Hydrometer Liquids — hydrometers for measuring the specific gravity of light and heavy liquids directly.
- Hoffman Clip — a plated tube clip, useful as a spare for closing the rubber tube.
- Rubber Tubing — natural rubber tubing for replacing the suction tube.
