Boyles Law Apparatus
Product Code : SCL-PLE-11810
Quick Answer: The Boyles Law Apparatus is used to study the pressure-volume relationship of a gas, with twin 220 mm borosilicate glass tubes, one open and one closed, on a cast iron base. A 0 to 100 cm scale with mm graduations and a sliding bracket system let pressure be changed and read by hand.

About This Product
Raising or lowering the open tube changes the pressure on the trapped air in the closed tube, and students record how its length changes to show that pressure and volume vary inversely at constant temperature. The readings can be plotted as P against 1/V and used to discuss experimental error and atmospheric pressure corrections. Educational Instrument can dispatch the Boyles Law Apparatus to laboratories in Georgia, Vietnam, Indonesia, Burkina Faso, Armenia and Estonia.
Frequently Asked Questions
How is pressure varied in the Boyles Law Apparatus?
The sliding bracket system lets the glass tubes be moved along the vertical rod, which changes the pressure on the trapped gas while the scale gives the readings.
