Gas Laws Demonstration w/Temperature & Pressure Gauges
by American Scientific

With its unique and compact design, this apparatus simplifies the Ideal Gas Law and the relationship that exists between the pressure, temperature and volume of a gas that remains constant. With a twist of the handle, you can compress or expand the air within the graduated cylinder. As it changes in either direction, note the changes in volume and temperature as the pressure is altered. The graduated cylinder is 29mm in diameter, and measures from 20 to 65mL in 5mL increments.

The apparatus has a cast iron base and features an on/off switch for the electronic thermometer. A brass vent can be manually opened or closed to relieve the pressure within the cylinder.

Dimensions measure approximately 160mm x 115mm x 208mm (L x W x H)
