Eisco Labs Boyle's Law Apparatus for Visual Study of Air Pressure and Volume of Gas

• Mounted on durable metal base
• Total height 8.3"
• Manometer dual scale is from 0 ? 4 x 105 Pa and 0 ? 58 PSI with needle set at atmospheric pressure
• Requires 1.5 v AA battery for operation

The Eisco Labs Boyle's Law Apparatus can be used to demonstrate the relationship between pressure and volume of gas. The unit consists of a 1.14" (29mm) dia. graduated cylinder with a piston and a screw valve. Cylinder acts upon a manometer through a narrow passage of 2.3" (60mm) dia. Manometer dual scale is from 0 ? 4 x 105 Pa and 0 ? 58 PSI with needle set at atmospheric pressure.
