Gay-Lussac’s Law apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12762
The Gay-Lussac’s Law Apparatus by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate the relationship between the pressure and temperature of a fixed mass of gas at constant volume. It is widely used in school science laboratories, college physics labs, STEM classrooms, and educational training institutes.
This apparatus helps students verify Gay-Lussac’s Law, which states that the pressure of a fixed amount of gas is directly proportional to its absolute temperature when the volume remains constant. By heating or cooling the gas chamber and observing the pressure change, students can clearly understand how temperature affects gas pressure.
The Gay-Lussac’s Law Apparatus is ideal for teacher demonstrations, student practicals, and laboratory experiments related to gas laws, pressure, temperature, thermodynamics, and kinetic theory of gases. Its clear measuring arrangement supports accurate observation and practical learning.

How to Use
Place the Gay-Lussac’s Law Apparatus on a clean, dry, and stable laboratory table.
Check all joints, tubes, valves, seals, and measuring parts before use.
Ensure that the gas chamber is properly sealed and the volume remains constant.
Note the initial temperature and pressure readings.
Heat the gas chamber gradually using the recommended heating method.
Record the corresponding pressure reading at different temperatures.
Allow readings to stabilize before noting each value.
Repeat the observation for multiple temperature points.
Compare the pressure and temperature readings.
Observe that pressure increases as temperature increases at constant volume.
Plot a graph of pressure against absolute temperature to verify Gay-Lussac’s Law.
After the experiment, switch off the heat source, allow the apparatus to cool, release pressure safely if required, clean the setup, and store it properly.
