Apparatus for Demonstrating the Boil-Marriott Law
Product Code : SCL-PLE-12358
The Apparatus for Demonstrating the Boil-Marriott Law (SKU SCL-PLE-12358) is a Boyle's law apparatus with a pressure gauge that shows, for a fixed mass of gas at constant temperature, that volume is inversely proportional to pressure (PV = constant). A transparent horizontal tube with a 0-300 cm3 scale is closed by a gas tap, and the pressure is read from a gauge beside the tap. JaincoLab supplies it for school and college gas-law practicals.
Specifications
The apparatus is built around a transparent tube mounted horizontally with a 0-300 cm3 volume scale, closed by a gas tap with a pressure gauge next to it; a rubber stopper sets the effective length of the tube and a movable cursor changes the volume during the experiment.

Applications of the Boyle's law apparatus with pressure gauge
The apparatus is used to verify Boyle's law: the trapped air is compressed or expanded by moving the cursor, and matching readings of volume on the scale and pressure on the gauge are recorded.
- Verifying that pressure times volume stays constant for a fixed mass of gas
- Plotting pressure against volume and against 1/volume from class readings
- Selecting different starting volumes with the rubber stopper
- Introducing the gas laws before Charles's law and the pressure law
- Gas-law practicals in senior secondary and college physics

Frequently asked questions
Which law does the apparatus demonstrate?
The Boyle-Mariotte law: for a given mass of gas at constant temperature, volume is inversely proportional to pressure, so PV is constant.
What volume range does the tube cover?
The transparent tube has a scale of 0-300 cm3.
How is pressure measured?
With a pressure gauge located next to the gas tap that closes the tube.
What should a quotation request include?
Send the SKU SCL-PLE-12358, the quantity and the delivery destination.
