Boyle’s Law Apparatus – Digital

The Digital Boyle’s Law Apparatus can be used to demonstrate the relationship between pressure and volume of gas.
It is capable of:

Enclosing volumes of air
Changing the volume and pressure of the air
Measuring pressures and volume changes

The unit consists of a 29mm diameter graduated cylinder with a piston and a screw valve. The cylinder acts upon a manometer through a narrow passage of 60mm diameter. The manometer dual scale is from 0–4 x 10^5 Pa and 0–58 PSI with the needle set at atmospheric pressure.

Mounted on durable metal base
Total height: 211mm
Manometer dual scale is from 0-4 x 10^5Pa and 0-58 PSI with needle set at atmospheric pressure
Requires 1.5 v AA battery for operation
Reasons to Love
Permits the exploration and validation of Boyle’s Law
Learning Outcomes
Key Stage 3 Chemistry – The particulate nature of Matter: The properties of the different states of matter (solid, liquid and gas) in terms of the particle model, including gas pressure.
Key Stage 4 Physics – The Structure of Matter: Links between pressure and temperature of a gas at constant volume, related to the motion of its particles (qualitative).  Explain why the work done in the compression or expansion of gases is the product of the pressure and the change in volume.
Top Tips
No external pump is required for this apparatus.
When the pressure control valve is fully open, the pressure gauge will read atmospheric pressure (not zero)
