Vacuum Tube and Manual Vacuum Pump
Product Code : JL-LEP-10366
The Vacuum Tube and Manual Vacuum Pump (SKU JL-LEP-10366) demonstrates the effect of air resistance on freely falling objects. The vacuum tube is a transparent acrylic tube at least 910 mm long containing a metal disc and a feather; once a hand-operated pump with pressure gauge has removed the air, both objects fall together when the tube is inverted. JaincoLab manufactures the set in India for school and college physics.
Specifications
The vacuum tube is transparent acrylic, at least 910 mm long and 55 mm in diameter, closed by a rubber stopper with a stopcock at one end and a solid rubber stopper at the other, and connects through 13-inch vinyl tubing to a sealed, self-lubricating hand pump with a pressure gauge and quick-release port.

Applications of the vacuum tube and pump
The set is used in lessons on gravity and free fall: students first watch the feather and disc fall at different rates in air, then repeat the drop after the air has been pumped out and see that both land together.
- Comparing the fall of a feather and a metal disc in air and in a partial vacuum
- Showing that, without air resistance, objects fall with the same acceleration
- Reading the pressure gauge as air is removed from the tube
- Discussing terminal velocity and drag in motion lessons
- Free-fall and gravity demonstrations in secondary and senior secondary physics
