Jolly Charles's Law Apparatus, 40"

The Eisco Labs Charles's Law Apparatus (Jolly Apparatus) provides precise experimental conditions for demonstrating that the volume of an ideal gas at constant pressure is directly proportional to its absolute temperature. The 40" tall apparatus features a 100cm vertical scale with 1mm graduations, mounted on an aluminum rail with a heavy metal base for whole-class visibility and stability. Two height-adjustable riders held to the rail with fly nuts support the included glass Jolly bulb and tubing assembly, and one rider includes a beaker support platform. The complete apparatus includes the vertical rail with scale, two riders, glass Jolly bulb, glass and flexible tubing, and setup instructions. An immersion thermometer or temperature sensor is required but not included. Overall size: 40"H on a 10" x 7" base.
