Boyle's Law Apparatus
Product Code : SCL-PLE-11771
Quick Answer: The Boyle’s Law Apparatus traps air in a transparent, thick-walled cylinder graduated in cm³, with an O-ring sealed piston to change the volume while the pressure is read, showing that pressure and volume are inversely proportional at constant temperature.

Key Features
- Transparent, thick-walled cylinder graduated in cm³/ml.
- Lubricated piston with high-pressure O-ring seals for smooth movement.
- Needle valve for letting air in and releasing pressure.
- Pressure reading taken at each piston position.
Technical Specifications
| Specification | Value |
|---|---|
| Cylinder | Transparent, thick-walled synthetic, graduated in cm³/ml |
| Piston | Lubricated, with high-pressure O-ring seals |
| Valve | Precision needle valve for air intake and release |
| Principle | Boyle’s law: P inversely proportional to V |
How It Is Used
Air is admitted through the needle valve, which is then closed to trap a fixed mass of gas. The piston is moved in steps, and at each step the volume is read from the cylinder graduations and the pressure noted. A graph of pressure against the reciprocal of volume gives a straight line, confirming Boyle’s law.
Frequently Asked Questions
How is the gas volume read on the Boyle’s Law Apparatus?
Directly from the graduations in cm³/ml on the transparent cylinder.
How is air let into or out of the Boyle’s Law Apparatus?
Through a precision needle valve, used for air intake and pressure release.
