Charles’Law apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12763
The Charles’ Law Apparatus by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate the relationship between the volume and temperature of a fixed mass of gas at constant pressure. It is widely used in school science laboratories, college physics labs, STEM classrooms, and educational training institutes.
This apparatus helps students verify Charles’ Law, which states that the volume of a fixed amount of gas is directly proportional to its absolute temperature when pressure remains constant. By heating or cooling the trapped gas and observing the change in volume, students can clearly understand how gases expand when heated and contract when cooled.
The Charles’ Law Apparatus is ideal for teacher demonstrations, student practicals, and laboratory experiments related to gas laws, temperature, volume, expansion of gases, and thermodynamics. Its clear measuring arrangement supports easy observation, accurate reading, and hands-on learning.

How to Use
Place the Charles’ Law Apparatus on a clean, dry, and stable laboratory table.
Check all glass parts, tubes, seals, clamps, and measuring scales before use.
Ensure the gas sample is properly enclosed and the pressure condition remains constant as per the experiment setup.
Note the initial temperature and volume reading.
Heat the water bath or gas chamber gradually using the recommended heating method.
Record the corresponding volume reading at different temperature values.
Allow readings to stabilize before noting each observation.
Repeat the observation for multiple temperature points.
Compare the volume and temperature readings.
Observe that gas volume increases as temperature increases at constant pressure.
Plot a graph of volume against absolute temperature to verify Charles’ Law.
After the experiment, switch off the heat source, allow the apparatus to cool, clean it, and store it safely.
