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

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.
