How Does It Compare with Other JLab Boyle’s Law Apparatus?
| Model | How pressure and volume are shown | Mounting |
|---|---|---|
| This apparatus (EL-SLE-4791) | Glass tubes joined by a rubber tube, lengths read on a metre stick | Wooden board on a cast-iron base |
| Boyles Law Apparatus Syringe Type | Graduated syringe; weights such as books placed on the top block vary the pressure | Between two wooden blocks |
| Boyle Law Apparatus | Gauge and syringe connected by a high-pressure hose | Perspex board |
| Boyle’s Law Apparatus | Liquid piston with hand-operated pumps; thermocouple and digital display | Self-contained bench-top unit |
Choose this apparatus for the traditional liquid-column method, where students read lengths on a metre stick and calculate pressure from level differences. The syringe-type sets suit quick demonstrations, and the self-contained bench-top unit adds a temperature display.
What Is the Boyles Law Apparatus Used For?
Boyle’s law states that, at constant temperature, the pressure of a fixed mass of gas is inversely proportional to its volume, so pressure multiplied by volume stays the same. In the two-tube arrangement, air is trapped in a closed tube and the second, open tube is raised or lowered on the board. The pressure on the trapped air is the atmospheric pressure plus or minus the difference between the two liquid levels, and, because the tube has a uniform bore, the length of the air column read on the metre stick stands for its volume. Students record several readings and plot pressure against the reciprocal of volume, which gives a straight line.
Take the day’s atmospheric pressure from a laboratory barometer, wait a minute or two after each adjustment so the trapped air returns to room temperature, and read each level at eye level to avoid parallax. Move the open tube slowly and keep the rubber tube free of kinks.
What to Specify When Ordering
- Tube arrangement — confirm whether you need the J-tube or the two-tube form described in the listing.
- Liquid — ask JLab which liquid the apparatus is set up for and whether it is supplied.
- Quantity — minimum 10 units; physics labs often equip one set per practical group.
- Barometer — add a barometer to read atmospheric pressure if your lab does not have one.
Frequently Asked Questions
What experiment is this apparatus for?
For verifying Boyle’s law, the relationship between the pressure and volume of a given sample of gas at constant temperature, in school and college labs.
What parts does it have?
The listing names a cast-iron base, a wooden board, a wooden metre stick, a J-shaped tube, and two glass tubes connected by a long rubber tube. Because a J-tube and a two-tube set are different designs, confirm the tube arrangement before you order.
Is the liquid for the tubes included?
The listing does not say. Ask JLab which liquid the apparatus uses and whether it is part of the supply.
How is pressure worked out in this experiment?
Add the difference in liquid levels to the atmospheric pressure when the open side is higher, and subtract it when it is lower. Atmospheric pressure is read from a barometer.
How is it different from the syringe-type Boyle’s law apparatus?
This set uses glass tubes and a metre stick on a cast-iron base; the syringe type uses a graduated syringe between wooden blocks, with weights placed on top to vary the pressure.
What should an export quotation request contain?
Quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling needs, and any tender reference.
Who manufactures this apparatus?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and school lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This apparatus is built in JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers buy it factory-direct, each set is inspected visually before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Cyprus in Southern Europe, Uzbekistan in Central Asia, Canada in North America, Benin in West Africa and Zimbabwe in East Africa. Tender information is available on the JLab lab tenders page.
