The P-648-30 is a Boyle's Gas Law Apparatus Advanced, easy to study and demonstrate the relationship between the pressure, temperature, and volume of a gas that is constant.

Excellent apparatus to study Boyle's Gas Law.  The volume of the air can be easily changed by turning the piston and the pressure and themperature can be noted from the gauges. By repeating the process, the law can be confirmed.
