Digital Boyles Law Apparatus

The Digital Boyle’s Law Apparatus provides a self-contained, reliable and simple way of demonstrating Boyle’s Law: the relationship between the volume, and pressure of a gas. The gas (air) volume may be reduced or increased by means of a 2.5 ml syringe on the front of the unit. The syringe connects to a digital pressure sensor, and pressure changes are witnessed when the gas volume is varied. The sensor output is calibrated to display the pressure in kPa on the easy-to-read LCD display. There is a measurable change in pressure for every 0.1 ml change in volume, allowing many data points to be taken and a graph plotted to confirm Boyle’s Law.

For teacher demonstration purposes, two 4 mm safety sockets are provided to allow the sensor output to be displayed on a large demonstration voltmeter (not supplied). Further, a length of tubing is provided to allow a larger syringe to be used, ideal for engaging, whole class demonstrations. Supplied with full instructions and one 9V PP3 battery.

Key features:

• Ideal for both student experimentation and teacher demonstration
• Digital read-out for easy data collection
• Simple conversion to SI units with pressure read-out in kPa
• Battery powered – no mains tethering restrictions
• Compact design for easy storage
